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.
Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

To start bnx2fc, we need to run fipvlan only and not dcbtool. DCBX is run
automatically in the hardware, but VLAN discovery needs to be started by
fipvlan.
