[PATCH 22/22] samples/bpf: Drop unnecessary build targets.

[Arnaldo Carvalho de Melo]

From: Joe Stringer <joe@xxxxxxx>

Commit f72179ef11db ("samples/bpf: Switch over to libbpf") added these
two makefile changes that were unnecessary for switching samples to use
libbpf. The extra make is already handled by the build dependency, and
libbpf target doesn't build because it lacks main(). Remove these.
