[PATCH 2/6] tools lib bpf: Avoid install_headers make warning

[Ian Rogers]

The perf build makes the install_headers target, however, as there is
no action for this target a warning is always produced of:

make[3]: Nothing to be done for 'install_headers'.

Solve this by adding a display of 'INSTALL libbpf_headers'.
