[llvm-mca] Make bad-input.s even more CPU specific

Note: This patch is distinct from the previous one titled
  "[llvm-mca] Move bad-input.s test to be target specific"

This is a followup to #90474 and commit
afc10fc

Context: Builders failing because they're unable to run the failure
test.

This still doesn't work in various circumstances, it seems MCA doesn't
want to run on a wide variety of hosts in various configurations, so
stick to the tried and tested method and pass -mtriple and -mcpu.
