RFR(XS): 8066106: sun/tools/jps/TestJpsClass.java failed to remove stale attach pid file

[Yekaterina Kantserova]

Hi,

Could I please have a review of this fix.

Since VM warnings go to stderr the suggested fix is to check only stdout 
for expected output and ignore warnings in stderr.

bug: https://bugs.openjdk.java.net/browse/JDK-8066106
webrev: http://cr.openjdk.java.net/~ykantser/8066106/webrev.00/

The tests have been run and passed on all basic platforms.

Thanks,
Katj
