8276819: javax/print/PrintServiceLookup/FlushCustomClassLoader.java fails to free

[mrserb]

This is an attempt to make the FlushCustomClassLoader more stable. I cannot reproduce this bug so added some improvement blindly, based on assumption that the test may fail on the slow/overloaded system.

• The attempt limitation was removed, but the test execution time decreased to 1 minute
• For each attempt the generation of OOM was added to make sure that the GC was triggered
