[OE-core][PATCH 1/2] lib: package: Add file_reverse_translate

[Joshua Watt <jpewhacker@gmail.com>]

Adds API to reverse the removal of special characters from file names so
it can be correctly done in multiple places without open-coding it.

Replace the translation done in the package_rpm.bbclass with the new API
