Subject: [PATCH bpf-next v5 03/12] bpf: selftests: Fix fentry test kfunc prototypes

Some prototypes in progs/get_func_ip_test.c were not in line with how the
actual kfuncs are defined in net/bpf/test_run.c. This causes compilation
errors when kfunc prototypes are generated from BTF.

Fix by aligning with actual kfunc definitions.

Also remove two unused prototypes.
