[gnome-continuous-yocto/gnomeostree-3.28-rocko: 2092/8267] build-perf-test-wrapper.sh: parse args with getopts

[Emmanuele Bassi <ebassi src gnome org>]

    build-perf-test-wrapper.sh: parse args with getopts
    
    Use getopts for parsing the command line. This changes the usage so that
    if a commit (to-be-tested) is defined it must be given by using '-c',
    instead of a positional argument.
