8347052: Update java man page documentation to reflect current state of the UseNUMA flag

[tschatzl]

Hi all,

please review this small fix to the man pages that previously stated that UseNUMA is only available with Parallel GC. To minimize future update problems, the text has been modified to just say that the default value is dependent on the collector.

Testing: local compilation

Thanks,
Thomas
