[8u] RFR (XS) 8153430: jdk regression test MletParserLocaleTest, ParserInfiniteLoopTest reduce default timeout

[Aleksey Shipilev]

Original fix:
  https://bugs.openjdk.java.net/browse/JDK-8153430
  https://hg.openjdk.java.net/jdk/jdk/rev/92cf8efd381d

MletParserLocaleTest.java was added by JDK-7065236 only in 9, so that hunk does not apply.
ParserInfiniteLoopTest.java hunk applies cleanly.

Testing: affected test
