doc: Force FOP to read images from doc directory

Looks like something changed and fop is now reading from the directory
containing the source file. xmlto places that source in /tmp, making
all relative URIs fail. Fix this by creating a fop configuration file
directing it to load relative to the doc directory and then pass that
through xmlto.
