Convert the s390x into s390 to also include s390-specific crypto
modules, for example, aes_s390 into the initramfs.

A LUKS root volume with a detached header on a device without partitioning will not have a UUID and will not have an attribute ENV{ID_FS_TYPE}=="crypto_LUKS".
Therefore, several areas need to be addressed: identification of the LUKS device, inclusion of entries within crypttab, and provision of the detached header file.
- Added support for an option (4th column: "force") in /etc/crypttab to force the inclusion of the entry in the initramfs version (avoiding the fs type test).
- Added support for an option (4th column: "header=/path/to/file") in /etc/crypttab to provide a path to a detached header file embedded within the initramfs.
- Added ID and PARTUUID support to the device (2nd column) in /etc/crypttab (complementing the existing UUID functionality).
- Added cmdline support to indicate LUKS device ("rd.luks.serial=") that refers to the attribute ENV{ID_SERIAL_SHORT}.
Tested successfully on Void Linux (x86_64 musl) (no systemd) with a LUKS root volume accessed with a keyfile and using a detached header.
Not tested on systemd, or on a LUKS root volume with a passphrase rather than a keyfile.
blkid is not available when this function is called, so block_uuid.map is put into
the initrd, mapping block devices from /etc/crypttab to UUIDs.
This fixes a bug where udev rules were created by mistake as crypttab_contains()
returned false for devices specified by path in /etc/crypttab which resulted in
error messages during boot.

This aligns other places piping cmdline() output to cmdline.d files
with the earlier fix for 95rootfs-block.

--no-hostonly-cmdline:

Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
This prints the kernel command line parameters for the current disk
layout.
$ dracut --print-cmdline
rd.luks.uuid=luks-e68c8906-6542-4a26-83c4-91b4dd9f0471
rd.lvm.lv=debian/root rd.lvm.lv=debian/usr root=/dev/mapper/debian-root
rootflags=rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered
rootfstype=ext4
Prevents following error message:
I: *** Including module: crypt ***
/usr/lib/dracut/modules.d/90crypt/module-setup.sh: line 31: /etc/crypttab: No such file or directory
In kernel_only mode, we don't want to write /etc/cmdline.d
Correctly return the check functions, so we have a valid return of
for_each_host_dev_fs().
mdraid and dmraid functions had wrong checkings for the filesystem
type.
Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.
