vmtest: add s390x blacklist

Browse Source 
A lot of tests in test_progs fail due to the missing trampoline
implementation on s390x (and a handful for other reasons). Yet, a lot
more pass, so disabling test_progs altogether is too heavy-handed.

So add a mechanism for arch-specific blacklists (as discussed in [1])
and introduce a s390x blacklist, that simply reflects the status quo.
