[PATCH] man: fix manpage build instructions

This fixes all the out-of-tree build-failures with manpages and uses a
.man_fixup file to avoid overriding man-pages on every build.

Manpages are only built if xsltproc is found and the stylesheets are
available locally. You can disable building manpages with
--disable-manpages so the quite expensive xsltproc procedure can be
skipped.

Hi

This is how I build manpages for kmscon and it worked until now so it should
also work for libdrm. I tried every kind of failure and out-of-tree builds and
everything worked. distcheck also passed fine.

I hope that fixes all issues.
Regards
David
