buried punishment ball

Prevent burying a ball from ending your punishment.

When you bury the ball, internally NetHack Punishment
ceases, but a new trap type of TT_BURIEDBALL  immediately
kicks in (acting similar to TT_INFLOOR in some ways).
You can eventually work the ball free (or teleport, etc.),
but that will just return you back to normal Punishment.
