selftests/bpf: Test_progs can read test lists from file

Improve test selection logic when using -a/-b/-d/-t options.
The list of tests to include or exclude can now be read from a file,
specified as @<filename>.

The file contains one name (or wildcard pattern) per line, and
comments beginning with # are ignored.

These options can be passed multiple times to read more than one file.
