====================
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.

Changelog:
v1 -> v2:
- added fixes tag for patch #1 (bot+bpf-ci);
- extended test cases for '!*foo*' and '*foo*' filters in patch #2
  (bot+bpf-ci);
- added patch #3, replacing direct read() calls with calls to
  read_output(), guaranteeing input buffer null termination
  (bot+bpf-ci).
