Correctly generate version.xml and reldate.xml

The buildsystem expects these files to be in srcdir, so
put them there. Otherwise documentation won't build
(xmlto complains that it can't find the files. Note that
it uses an absolute path, so there's no way to solve this
with its --searchpath argument).
