EventLoopTest: lower value in gt_LeakChecks for gcc11
Use TestParams{ 9000, 1 }
instead of TestParams{ 50000, 1 }
in gt_LeakChecks
- the latter causes unit-test failures since the AnalysisBase nightlies have been switched to gcc11.
Tagging @akraszna, @krumnack, @tadej who have changed this file in the past.
Fixes ATLASG-1610.
