RFR: JDK-8067254: No debug symbols in JPRT Windows builds

[Erik Joelsson]

Hello,

Please review this fix which returns debug info files to the windows 
images. In the modular image change I mistakenly filtered out the debug 
info files (by comparing the new images/jdk/bin dir with the old 
images/j2sdk-image/bin dir instead of images/j2sdk-image/jre/bin where 
the files used to be). I also had to patch the jimage build tool to make 
the .diz, .pdb and .map files end up in the bin dir.
