RFR 8134239(XS): compiler/arguments/CheckCICompilerCount.java still fails

[gerard ziemski]

Please review this trivial test change that updates CheckCICompilerCount test to match the constraints error message 
format, which changed before compiler/runtime repo sync took place with code that was still using the old format.
