perf test bpf: Free obj_buf

Browse Source 
commit 937654ce497fb6e977a8c52baee5f7d9616302d9 upstream.

ASan reports some memory leaks when running:

  # perf test "42: BPF filter"

The first of these leaks is caused by obj_buf never being deallocated in
__test__bpf.

This patch adds the missing free.
