[gnome-continuous-yocto/gnomeostree-3.28-rocko: 2077/8267] oe-build-perf-test: implement --run-tests option

[Emmanuele Bassi <ebassi src gnome org>]

commit c284616ffb994915bcb31b731c565c4426190faa

    oe-build-perf-test: implement --run-tests option
    
    Makes it possible to run only a subset of tests.
    
    NOTE: The tests currently have (unwritten) dependencies on each other so
    use this option with care. Mainly for debugging.
