libperf: Change tests to single static and shared binaries 

Make tests to be two binaries 'tests_static' and 'tests_shared', so the
maintenance is easier.

Adding tests under libperf build system, so we define all the flags just
once.

Adding make-tests tule to just compile tests without running them.
