[tracker/sam/functional-tests-shared: 16/21] functional-tests: Remove obsolete options

    functional-tests: Remove obsolete options
    
    The old 'verbose' option isn't needed. The tests should be silent by
    default, and noisy when TRACKER_VERBOSITY > 1 or TRACKER_TESTS_VERBOSE
    is set.
    
    The old 'manual start' option is also removed. If you need to attach a
    debugger to one of the Tracker daemons during a test, my advice is to
    modify the code to add a `g_sleep(10000)` call early in startup, start
    the test in question, and then manually attach `gdb`.
