RFR [XS] : 8210961: [aix] enhance list of environment variables reported in error log file on AIX

[Baesken, Matthias]

Hi Volker, sure  the LDR_PRELOAD might not be so important any more these days .
However it might be  fine to have it included in the list of environment variables for the sake of completeness ( in it is maybe of interest in cases where we start
   other  (32bit) binaries  from java ).

Best regards, Matthias
