selftests/bpf: Adapt assert_mprog_count to always expect 0 count
Simplify __assert_mprog_count() to remove the -ENOENT corner case as the
bpf_prog_query() now returns 0 when no bpf_mprog is attached. This also
allows to convert a few test cases from using raw __assert_mprog_count()
over to plain assert_mprog_count() helper.
