[llvm] [llvm-exegesis][unittests] Disable SubprocessMemoryTest on big-endian… (PR #102755)

There is only one test here that should actually be dependent on endianness (the one marked explicitly).

I've never run this test on a big-endian system myself to debug, so I can't say for sure, but I would suspect that there is a different issue (the zero value is really suspicious from your test failures)

Ultimately though, this test is for functionality that is only enabled on x86_64. I'd rather not carve out x86_64 specifically to prevent people missing this on bringup though.

I'm not opposed to this patch, but I'd probably prefer a carve out specific to Sparc pending more investigation.
