par_master: Add shutdown function in par_master struct

With this, register_par_master can take care of register_shutdown
as well, and every par master only needs to call
register_par_master instead of calling both register_par_master
and register_shutdown.

Next patches in the chain convert par masters to use new API.

BUG=b:185191942
TEST=builds and ninja test
