try simple @build fix in compiler/jsr292/PollutedTrapCounts.java

I think this test fails a lot because it happens to be run soon after another test that causes a library split (see my analysis in CODETOOLS-7901986). So instead of quarantining it, maybe it's better to fix it by:

diff -r d1f8431c6d34 test/compiler/jsr292/PollutedTrapCounts.java

  */

This seems generally safe (and will not make the situation worse) because the test is very simple and it's use of '@library /test/lib' is straightforward.
