Description of problem:

In my automatic rebuild of Python packages I use the special `+auto` argument with %pyproject_save_files.
This uncovered an issue with man pages. If upstream includes a man page to its package data, it becomes compressed by RPM brp-compress script, and as a result changes the extension (i.e. example.1 becomes example.1.gz). The file example.1 is then looked for and not found, which results in failed RPM build, even though the actual build process went just fine.

It would be nice to have %pyproject_save_files go through the same directories as RPM does when it looks for man pages and append asterisk to each filename (i.e. example.1 becomes example.1*) as defined in the Fedora Packaging Guidelines: https://docs.fedoraproject.org/en-US/packaging-guidelines/#_manpages. 

Note: RPM hard codes the paths it traverses when looking for man pages to compress. Until they're provided as a macro, we'll have to maintain a list of the directories in pyproject macros as well.
