Andrii Nakryiko cbdb1461dc selftests/bpf: Use explicit bpf_prog_test_load() calls everywhere
-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and
breaks when deprecation goes into effect due to macro magic. Convert all
the uses to explicit bpf_prog_test_load() calls which avoid deprecation
errors and makes everything less magical.
