block: Add bdrv_default_perms()
This callback can be used by BDSs that use child_of_bds with the
appropriate BdrvChildRole for their children.
Also, make bdrv_format_default_perms() use it for child_of_bds children
(just a temporary solution until we can drop bdrv_format_default_perms()
altogether).
