Consider dropping compressdocs.sh with our own implementation for compressed man pages

Copied from the commit message:

This works as-is, however, we may want to drop compressdocs.sh with our own implementation in python. It will need to:

• Determine man page files or just walk $installdir/usr/share/man $installdir/usr/man
• Skip compression if already compressed (look for .gz, .bz2 append)
• Compress with the highest level of gzip compression and append with .gz
• Look for hardlinks or symlinks and handle them as needed

FWIW man-db 2.9.2 also added support for zstd-compressed man files.

Thanks, zstd would work as well! The man pages will compress pretty well either way but i don't think python 2.7 supports zstd compression so we'll have to call out to the zstd binary directly if we went that way.
