[PATCH v2 05/22] Remove last cleanup from gdbserver

[Tom Tromey]

This removes the last cleanup from gdbserver, replacing it with
SCOPE_EXIT.  This could perhaps be done in a different way, but this
approach was direct and obviously correct.

	* server.c (detach_or_kill_for_exit_cleanup): Remove parameter.
	(captured_main): Use SCOPE_EXIT.
