OK, applied with some slight modifications so that --initrd is only
accepted for kvm-xfstests.

BTW, I tried using the Fedora 24 kernel, and there's something wonky
with the serial console.  It looks like every other character which is
typed is getting eaten.  I suppose it's good to be able to test with
random distribution kernels with initrds, but there may be weird
compatibility issues with different distro's initrds, so I am a bit
worried that this might be a bit of a support headache in the long
term.
