In case of "--no-hostonly-default-device", we do not need
the root device, thus add this check.
Also fixed the stale "root_dev" export.

Kdump doesn't need default host devices like root, swap, fstab, etc,
we only care about the dump target which can be added via "--mount"
or "--add-device". We met several issues that kdump kernel failed
due to one of those host devices added by dracut, additionally, the
needless devices(e.g. LVM) consume some appreciable amount of memory
which is more likely to cause OOM under memory-limited kdump.
So this patch introduced "--no-hostonly-default-device" to avoid
adding those default devices as host_devs.

If we trigger crash just after creating initramfs, sometimes it is
observed that initramfs is not written to disk causing the subsequent
boot to fail. A sync should resolve this.

This is intended for minimum host OSes where 36 MB used by binutils
are deemed too expensive. We only need "strip", which exists as eu-strip
in elfutils, which in turn is < 1 MB in size.
Note that the tests (TEST-04-FULL-SYSTEMD/test.sh) still depend on
strip from binutils. It could use sstrip in the future.
The default output filename for --uefi is
<EFI>/EFI/Linux/linux-$kernel$-<MACHINE_ID>-<BUILD_ID>.efi.
<EFI> might be /efi, /boot or /boot/efi depending on where the ESP partition
is mounted. The <BUILD_ID> is taken from BUILD_ID in /usr/lib/os-release or
if it exists /etc/os-release and is left out, if BUILD_ID is non-existant or
empty.
Also a new option --no-machineid was added, which affects the default output
filename of --uefi and will discard the <MACHINE_ID> part.
Dracut changes working directory before attempting to output files under
$DRACUT_TMPDIR , resulting in an IO failure if $DRACUT_TMPDIR is a path
relative to the working directory when dracut was started.

Handle module aliases correctly to not generate unbootable
initrds with different kernel versions when modules were renamed
or replaced.

If the directory where the .img file is saved has no enough space, or in
other wrong conditions, dracut will get an incomplete file xxx.img. But
sometimes this .img file will be loaded when rebooting the system. And then
some bugs will happen because this .img file is wrong.
So I think dracut should remove the incomplete file because this .img file
with problems was made by dracut. And then the wrong file will not be loaded
anymore.
