Support for eppic language as a subpackage

This feature enables us to specify rules to scrub data in a
dumpfile with eppic macro instead of the current configuration
file (makedumpfile.conf). Currently, this feature works only
for symbols in vmlinux while the current feature can work also
for module symbols.

This library is backported from upstream, integrated and tested by
Dave Anderson.
