perf trace: empty fix libbpf 1.0+ compatibility

Avoid use of tools/perf/include/bpf/bpf.h and use the more regular BPF
headers.  Add raw_syscalls:sys_enter to avoid the evlist being empty.

Committer testing:

  # time perf trace -e ~acme/git/perf/tools/perf/examples/bpf/empty.c sleep 5

  real	0m5.697s
  user	0m0.217s
  sys	0m0.453s
  #

I.e. it sets up everything successfully (use -v to see the details) and
filters out all syscalls, then exits when the workload (sleep 5)
finishes.
