Use older grub for _support_server tftp to fix PXE (#2152763)

Browse Source 
PXE install on UEFI (incl. aarch64) is failing at present, this
seems to be due to a grub bug:
https://bugzilla.redhat.com/show_bug.cgi?id=2152763
we're really intending to test the client side here, not the
server end, so let's work around this problem on the server end
by installing a grub2 scratch build that's the package from just
before the bad change, but with the release and epoch bumped,
from a side repo.
