Since e145242ea0 ("syscalls/core, syscalls/x86: Clean up syscall stub
naming convention") changed the main syscall function for 'epoll_pwait'
to something other than the expected 'SyS_epoll_pwait the' 'perf test
BPF' entries started failing, fix it by using something called from the
main syscall function instead, 'epoll_wait', which should keep this test
working in older kernels too.

Before:

  # perf test BPF
  40: BPF filter                           :
  40.1: Basic BPF filtering                : FAILED!
  40.2: BPF pinning                        : Skip
  40.3: BPF prologue generation            : Skip
  40.4: BPF relocation checker             : Skip

If we use -v for that test we see the problem:

    Probe point 'SyS_epoll_pwait' not found.

After:

  # perf test BPF
  40: BPF filter                           :
  40.1: Basic BPF filtering                : Ok
  40.2: BPF pinning                        : Ok
  40.3: BPF prologue generation            : Ok
  40.4: BPF relocation checker             : Ok
