bus: replace ENOSYS return codes with EBADR/ENOTSUP

ENOSYS is used to signify compiled-out functionality. Using it for
different kinds of error is misleading.

For BUS_ERROR_SLEEP_VERB_NOT_SUPPORTED, logind-action.c uses ENOTSUP
already, so changing it to ENOTSUP makes the dbus and action paths
behave the same.
