selftests/bpf: Test stack depth stats without BTF subprog names

Browse source

Test the per-program insns_self, insns_total, and stack depth statistics
emitted when BTF function info does not provide subprogram names. Check that
the subprog 0 main record and static-subprogram records use <unknown>.

Make VERBOSE_ACCEPT request verifier statistics so the raw-insn test can
validate the output without a test-specific log level.
