audio: Set test timeout for effect tests back to 10m

For b/350998390, we have increased the timeout for "Core"
tests to `30m`. As it was suggested on b/350998390#comment11,
tests for "Effect" should retain `10m` timeout. It is now
possible to make this change as the XML config files for tests
were split.
