[PATCH app-xinit 1/3] Use XORG_MANPAGE_SECTIONS rather than cpprules.in to build man pages

[Gaetan Nadon]

As for all other manpages, use sed rather than the C preprocessor
from the Imake days.

Use SCOMAN Automake variable and groff .if for conditional text
We can therefore remove ARCHMANDEFS
Remove man page related code from cpprules.in
