[PATCH] bpf: Fix test_verifier after introducing resolve_pseudo_ldimm64

[Hao Luo]

Commit 4976b718c355 ("bpf: Introduce pseudo_btf_id") switched
the order of check_subprogs() and resolve_pseudo_ldimm() in
the verifier. Now an empty prog and the prog of a single
invalid ldimm expect to see the error "last insn is not an
exit or jmp" instead, because the check for subprogs comes
first. Fix the expection of the error message.

Tested:
 # ./test_verifier
 Summary: 1130 PASSED, 538 SKIPPED, 0 FAILED
 and the full set of bpf selftests.

Fixes: 4976b718c355 ("bpf: Introduce pseudo_btf_id")
