[PATCH bpf-next 0/2] selftests/bpf: fix for veristat file/prog filters processing

At the moment veristat filtering behaves unexpectedly for the
following filter expression:

  -f !file/prog

The expression rejects all programs with name 'prog', and all programs
in a file with name 'file'. Fix the expression to exclude only a
program 'prog' from a file 'file', also add a set of tests to exercise
filtering logic.
