Add bpf_testmod module, which is conceptually out-of-tree module and provides ways for selftests/bpf to test various kernel module-related functionality: raw tracepoint, fentry/fexit/fmod_ret, etc. This module will be auto-loaded by test_progs test runner and expected by some of selftests to be present and loaded. Pahole currently isn't able to generate BTF for static functions in kernel modules, so make sure traced function is global.
