selftests/bpf: Fix test_verifier after introducing resolve_pseudo_ldimm64
Commit 4976b718c355 ("bpf: Introduce pseudo_btf_id") switched
the order of check_subprogs() and resolve_pseudo_ldimm() in
the verifier. Now an empty prog expects to see the error "last
insn is not an the prog of a single invalid ldimm exit or jmp"
instead, because the check for subprogs comes first. It's now
pointless to validate that half of ldimm64 won't be the last
instruction.
Tested:
# ./test_verifier
Summary: 1129 PASSED, 537 SKIPPED, 0 FAILED
and the full set of bpf selftests.
Fixes: 4976b718c355 ("bpf: Introduce pseudo_btf_id")
