[python, tests] Disable Clang Python tests on SPARC

[ro]

Summary

Running make check-all fails on Solaris 11/SPARC since the clang python tests FAIL:

Ran 126 tests in 2.123s

FAILED (failures=2, skipped=6)

Unfortunately, this aborts the rest of `make check-all`, even with `-k`, so this patch
disables the test as is already done on a couple of other targets.

This allowed the `sparc-sun-solaris2.11` test to finish.

Ping? Who's an appropriate reviewer here? CODE_OWNERS.TXT doesn't list anyone.

Just add it to the regex above.

[ro]

Skip SPARC like other targets.

Done now. Initially I tried to check if it's also the ffi issue, until I noticed that some targets were skipped there for different reasons.
I cannot check anything but Solaris/SPARC, though, but assume that it's a generic SPARC issue, nothing Solaris-specific, given that Solaris/x86
passes the test.

Thanks, looks good. Do you have commit access or do you need me to commit it for you?

I do have commit access, so I'll do it myself. Thanks.
