gbm: use the loader util lib

Additionally this commit removes the following exported functions

   _gbm_udev_device_new_from_fd()
   _gbm_fd_get_device_name()
   _gbm_log()

All three were erroneously marked as exported since their inception.
Neither of them has ever been a part of the API thus there should be
no users of them.
