selftests/bpf: Fix up btf/invalid test for extended kind

Browse Source 
With extended kinds, 32 becomes a valid (but not used)
BTF info kind value; fix up the test to check for the
"Invalid kind" rather than "Invalid btf_info" message.
Since all bits are used in BTF info, it is no longer
possible to craft an invalid BTF info value.  Use
127 (new maximum possible kind value).
