Subject: [PATCH] Autotools: Re-work handling of xmlwf.1

File "doc/xmlwf.1" should not be cleaned when building with
"./configure --without-docbook", and re-compilation of the file
should take precedence over a pre-built copy where available.

Also, variable CLEANFILES can be used to simplify things a bit
in Makefile.am.
