perf build: Install libsubcmd locally when building

Browse source 
The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf headers are all found via this path, making it impossible to
override include behavior. Change the libsubcmd build mirroring the
libbpf build, so that it is installed in a directory along with its
headers. A later change will modify the include behavior.
