lib: simplify installation of libbpf and libxdp submodule libraries

Browse Source 
Instead of having the someone redundantly named 'lib/lib-install' folder,
let's rename it to just 'lib/install', and drop the 'usr/' prefix of the
files installed into that directory. Also, to simplify the configure
script, check in the directory to git so it's always present, and always
include it in the include and linker paths. On clean we just clear out the
contents.

Also, copy over libbpf.a to lib/install/lib alongside libxdp.a instead of
putting libbpf/src in the linker path.
