bpftool: Skeleton should depend on libbpf
Add the dependency to libbpf, to fix build errors like:
In file included from skeleton/profiler.bpf.c:5:
.../bpf_helpers.h:5:10: fatal error: 'bpf_helper_defs.h' file not found
#include "bpf_helper_defs.h"
^~~~~~~~~~~~~~~~~~~
1 error generated.
make: *** [skeleton/profiler.bpf.o] Error 1
make: *** Waiting for unfinished jobs....
Fixes: 47c09d6a9f67 ("bpftool: Introduce "prog profile" command")
