[gnome-video-arcade] Do not monitor non-existent directories.

    Do not monitor non-existent directories.
    
    Do not create a GFileMonitor for a directory that doesn't exist.  This
    doesn't seem to be an issue on Linux, but on OpenBSD at least the file
    monitor trips immediately with a G_FILE_MONITOR_EVENT_DELETED, which
    causes GVA to ask on startup if it should re-analyze ROMs.
    
    What exposed this issue was the fact that the MAME package on OpenBSD
    includes $HOME/.mame/roms in the default ROM path, but that directory
    will not exist in a newly-created user account.
    
    Related to GNOME bug #652465.
