[LTP] [PATCH] vmcp: skip test on non-s390x architectures

[Sowmya Indranna]

Agree, the test results in failed state when run which should be part of skip tests, complete details are in the issue https://github.com/linux-test-project/ltp/issues/1298 for reference.

Thanks

The test has TST_NEEDS_CMDS="vmcp" it shouldn't even start unless there
is vmcp installed. And would expect that vmcp is not installed unless we
are on s390x.
