RFR: 8366222: TestCompileTaskTimeout causes asserts after JDK-8365909

[Manuel Hässig]

This PR increases the timeout of the positive test case in `compiler/arguments/TestCompileTaskTimeout.java`, because it was too low, such that the test case failed on some systems. The new timeout of 2s should be large enough for all systems.

Testing:
 - [ ] Github Actions
 - [ ] tier1,tier2 Linux fastdebug x64, aarch64
