Orphaned processes that are being traced are killed by the

kernel.  Properly restore, continue, and detach from processes
being DTraced when DTrace exits with an error so the program
being inspected is not terminated.

cddl/contrib/opensolaris/cmd/dtrace/dtrace.c:
	In fatal(), the generic error handler, close the DTrace
	handle as is done in the "probe/script" error handler
	dfatal().  fatal() can be invoked after DTrace attaches
	to processes (e.g. a script specified by command line
	argument can't be found) and closing the handle will
	release them.
