perf tests clang: Fix function name for clang IR test 

As stated in tests/llvm-src-base.c, the name of the bpf function should
be "bpf_func__SyS_epoll_pwait" but this clang test fails as it tries to
lookup "bpf_func__SyS_epoll_wait".

Before applying patch:

55: builtin clang support                                 :
55.1: builtin clang compile C source to IR                : FAILED!
55.2: builtin clang compile C source to ELF object        : Skip

After applying patch:

55: builtin clang support                                 :
55.1: builtin clang compile C source to IR                : Ok
55.2: builtin clang compile C source to ELF object        : Ok
