[PATCH 2/7] Makefile: Improve uninstall target for compressed man pages

[Alexander Miller <alex.miller-Mmb7MZpHnFY@public.gmane.org>]

Now sources and installed man pages may be in plain/gz/bz2/xz
format (independently). Any combination works reliably.

I would have preferred find -print0, but sed is line-based. As long
as there are no man page filenames with newlines, that's good enough.
