libmakepkg: make package tidy functions extendable

To add a new packaging option, drop a file into libmakepkg/tidy that contains
a 'packaging_options+=('<option>') and a function that implements that
option. The function needs added to the 'tidy_remove' array if it removes
files or the 'tidy_modify' array otherwise.
