[PATCH bpf-next v2 2/3] selftests/bpf: Add test_usdt_multispec.inc.h for sharing between multiple progs

[Yonghong Song <yonghong.song@linux.dev>]

Replace test_usdt_multispec.c to test_usdt_multispec.inc.h so the bpf prog
usdt_100 can be used for multiple bpf programs. The newer test_usdt_multispec.c
will just include test_usdt_multispec.inc.h.
