Add --disable-man configure option

This matches what is available in glib.  Allowing documentation
to be disabled is good for 3 reasons:

1) Embedded system developers don't want it - while it's not too
   hard for them to just rm -rf /usr/share/man, it makes sense
   to just skip building it entirely.
2) Documentation is the source of build dependency loops; having
   a method to disable it allows those loops to be cut manually
3) My gnome-ostree build system doesn't include Docbook because
   the schemas are only distributed as Zip files, and the build
   system only accepts git repositories.
