[clang] [Clang][Test] Mark modules-symlink-dir test as unsupported on AIX. (PR #184988)

[Aditya Chaudhary via cfe-commits]

https://github.com/aditya-chaudhary1 created https://github.com/llvm/llvm-project/pull/184988

This change marks the test `modules-symlink-dir-from-module-incremental.c` as "unsupported" on AIX. The test relies on the -F flag to specify framework search paths, which is a driver feature exclusive to Darwin, and it is not supported on the AIX target.
