Subject: bpf: install libbpf headers on 'make install'
Patch-mainline: v4.14-rc1
Git-commit: eb54e522a000b8e625e03282fd434fb725a530c0
References: bsc#1109837

Add a new target to install the bpf.h header to $(prefix)/include/bpf/
directory.  This is necessary to build standalone applications using
libbpf, without the need to clone the kernel sources and point to them.
