perl: Improve ptest package reproducibility

Fixes a few reproducibility issues in the perl ptest package:
 1) config.log has a lot of paths encoded in it. This file is
    unnecessary for ptest, so it is omitted from the package
 2) Makefile.config has a lot of paths encoded in it. This file should
    be fixed up using the same rules as several other files that are in
    the package
 3) Paths in DEBUG_PREFIX_MAP are not being correctly removed from files
    because DEBUG_PREFIX_MAP is now several command line arguments.
    Instead of requiring an exact match for all arguments, remove any
    matching argument.
