Subject: [PATCH 1/7] 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.
