RFR: JDK-8055352: AIX hprof should include its own copy of dladdr in porting_aix.c

[Erik Joelsson]

Hello,

Please review this minor fix for hprof demo on aix. When reorganizing 
the source code for modules, we put a copy of 
src/aix/porting/porting_aix.* in each of the two locations using it. One 
of them was the hprof demo. This patch removes the now unused extra 
source dir declaration for hprof.
