runtime: remove arbitrary 5-second timeout in TestNeedmDeadlock
The NeedmDeadlock test program currently has a 5-second timeout,
which is sort of arbitrary. It is long enough in regular mode
(which usually takes 0.0X seconds), but not quite so for
configurations like ASAN. Instead of using an arbitrary timeout,
just use the test's deadline. The test program is invoked with
testenv.Command, which will send it a SIGQUIT before the deadline
expires.
Fixes #56420 (at least for the asan builder).
