[OSSTEST PATCH 12/12] abolish "kernkind"; desupport non-pvops kernels

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

This was for distinguishing the old-style Xenolinux kernels from pvops
kernels.

We have not actually tested any non-pvops kernels for a very very long
time.  Delete this now because the runvar is slightly in the way of
test host reuse.

(Sorry for the wide CC but it seems better to make sure anyone who
might object can do so.)

All this machinery exists just to configure the guest console
device (Xenolinux used "xvc" rather than "hvc") and the guest root
block device (Xenolinux stole "hda"/"sda" rather than using "xvda").

Specifically, in this commit:
 * In what is now target_setup_rootdev_console_inittab, do not
   look at any kernkind runvar and simply do what we would if
   it were "pvops" or unset, as it is in all current jobs.
 * Remove the runvar from all jobs creation and example runes.
   (This has no functional change even for jobs running with
   the previous osstest code because we have defaulted to "pvops"
   for a very long time.)

We retain the setting of the shell variable "kernbuild", because that
ends up in build jobs names.  All our kernel build jobs now end in
-pvops and I intend to retain that name component since abolishing it
is nontrivial.
