RFR [XS]: 8233219: NMT output on AIX misses some categories

[Baesken, Matthias]

Hello, please review this small  fix .

I noticed that since ~ end or March 2019,   some  sections  especially the "Java Heap" category  were missing from NMT output  on AIX .

Also the category "Test" ( Test type for verifying NMT ) that is tested by a few NMT related tests is missing ,  which  caused most of  the runtime/NMT tests to fail .
The following small fix brings  the Java Heap  categogy back and fixes also  the  runtime/NMT tests on AIX .

Thanks to  Zhengyu   for pointing me into the right direction when looking into the issue .
