The test_bpftool_map.sh script tests that maps read/write accesses
are being properly allowed/refused by the kernel depending on a specific
fmod_ret program being attached on security_bpf_map function.

Rewrite this test to integrate it in the test_progs. The
new test spawns a few subtests:

  #36/1    bpftool_maps_access/unprotected_unpinned:OK
  #36/2    bpftool_maps_access/unprotected_pinned:OK
  #36/3    bpftool_maps_access/protected_unpinned:OK
  #36/4    bpftool_maps_access/protected_pinned:OK

  #36/6    bpftool_maps_access/btf_list:OK
  #36      bpftool_maps_access:OK
  Summary: 1/6 PASSED, 0 SKIPPED, 0 FAILED
