Don't cancel the alarm on exec*(). POSIX alarm() requires that. The BeBook

doesn't mention the expected set_alarm() behavior. Tests under BeOS R5 Bone
crash the system in either case, though, so I guess we're free to go with the
expected POSIX behavior.
This make detection of hanging tests in the Open POSIX Test Suite work.
