[libcxx] [test] Don't detect Windows' UCRT with TEST_COMPILER_C1XX

[BillyONeal]

Summary

The test is trying to avoid saying aligned_alloc on Windows' UCRT, which does not (and can not) implement aligned_alloc. However, it's testing for c1xx, meaning clang on Windows will fail this test when using the UCRT.

[BillyONeal]

Also fixed cstdlib tests.

Looks fine to me

Thank you! :D
