[clang] [clang-fuzzer] Remove GCC 4.9 workaround to silence warning (PR #73974)

[Brad Smith via cfe-commits]

https://github.com/brad0 created https://github.com/llvm/llvm-project/pull/73974

The minimum GCC version was bumped up from 4.8 to 5.1 and then even newer awhile ago so garbage collect the 4.9 workaround.
