build-sys: provide fallback value for xsltproc
Commit ab6f56debf made the change to allow building man pages even when disabled with ./configure --disable-manpages. This works fine, as long as xsltproc is present. If xsltproc is not present, the command to build a man page (obviously) fails. Unfortnately it fails with a cryptic message '-o not found', because $(XSLTPROC) is empty. Add a fallback, to use 'xsltproc' is $(XSLTPROC) is not defined. This way we get a nice message: make: xsltproc: Command not found
