67faabbde3
Adding missing prototypes for several kfuncs that are used by
test_verifier tests. We don't really need kfunc prototypes for
these tests, but adding them to silence 'make W=1' build and
to have all test kfuncs declarations in bpf_testmod_kfunc.h.
Also moving __diag_pop for -Wmissing-prototypes to cover also
bpf_testmod_test_write and bpf_testmod_test_read and adding
bpf_fentry_shadow_test in there as well. All of them need to
be exported, but there's no need for declarations.
