====================
bpf: selftests fixes for GCC-BPF 16

Hello.

Just a couple of small fixes to get the BPF selftests build with what
will become GCC 16 this spring.  One of the regressions is due to a
change in the behavior of a warning in GCC 16.  The other is due to
the fact that GCC 16 actually implements btf_decl_tag and
btf_type_tag.

Salud!
