selftests/bpf: fix test_loader check message

Seeing:

  process_subtest:PASS:Can't alloc specs array 0 nsec

... in verbose successful test log is very confusing. Use smaller
identifier-like test tag to denote that we are asserting specs array
allocation success.

Now it's much less distracting:

  process_subtest:PASS:specs_alloc 0 nsec
