[PATCH bpf-next v2] bpf: Clean up Makefile of bpf preload

[Yuntao Wang]

The trailing slash in LIBBPF_SRCS is redundant, it should be removed.

But to simplify the Makefile further, we can set LIBBPF_INCLUDE to
$(srctree)/tools/lib directly, thus the LIBBPF_SRCS variable is unused
and can be removed.
