RFR: 8255463: java/nio/channels/spi/SelectorProvider/inheritedChannel/InheritedChannelTest.java failed with ThreadTimeoutException

[Jaikiran Pai]

Can I please get a review of this test-only change which removes the testng specific timeout from a test method? 

As noted in https://bugs.openjdk.org/browse/JDK-8255463, the `test/jdk/java/nio/channels/spi/SelectorProvider/inheritedChannel/InheritedChannelTest.java` fails intermittently with:


test InheritedChannelTest.test("StateTest", java.util.ImmutableCollections$List12 at d28f210): failure [30001ms]
org.testng.internal.thread.ThreadTimeoutException: Method InheritedChannelTest.test() didn't finish within the time-out 30000

With the proposed change in this PR, it now relies on jtreg test timeout (default of 120 seconds). If the test continues to timeout for whatever reason, then jtreg will be able to capture the relevant thread dumps of the incomplete process (launched in this test method) to help debug the issue.

The existing 30 second timeout on the test method doesn't play any role in what the test verifies, so removing it doesn't change that verification.
