Ruud van Asseldonk ed81545df5 squashfsTools: 4.5 -> 4.5.1 
The patch that was previously fetched from GitHub is now part of the
4.5.1 release, and is no longer needed. Furthermore, 4.5.1 introduces
some new scripts to build manpages, and some new build inputs are
required to make that work.

This also rebases the Darwin patch. I don't have a Mac so I can't test
this personally. There was one conflict:
