genprotimg|zipl: build debuginfo files

Browse Source 
Currently, the debug information of the bootloader is discarded during
the raw binary creation. Change this by creating separate
<loader>.bin.debug files containing the debug information. The packager
will then be able to package these files as desired and the developer
can use them to debug the code.
