[clang] [Clang][NFC] Fix a test failure with mold linker (PR #122587)

[Younan Zhang via cfe-commits]

https://github.com/zyn0217 created https://github.com/llvm/llvm-project/pull/122587

Mold prefers the suffix '$' for symbols like PLT and GOT entries, so exclude these symbols as well. Otherwise, this test will fail for developers using mold-linked Clang.
