    common: Handle mount_prefix by g_mount_spec_set
    
    mount_prefix is set to the value "/export" if you e.g. call the following:
    gvfs-mount nfs://localhost/export
    
    Unfortunatelly, it is not possible to execute backend manually with a
    concrete mount_prefix. Handle key "prefix" as mount_prefix, so you can
    now execute backend manually with prefix, e.g.:
    /usr/libexec/gvfsd-nfs host=localhost prefix=/export
