====================
selftests/bpf: Fix compilation with RELEASE=1

When compiling BPF selftests with RELEASE=1 (which most notably adds
-O2), GCC reports several warnings. These are by default treated as
errors and abort the compilation.

This series fixes all of the issues such that selftests can be compiled
with RELEASE=1.
