Nowadays, we have a dependency chain cargo/rust -> librsvg -> graphviz-gd -> presage -> fcitx -> (everything and the kitchen sink). Remove the dependency on graphviz-gd and thus on rust.
- Split out API doc generation using multibuild. graphviz-gd has
become quite heavy as a build dependency.
- Cleanup specfile
* remove defattr, use license macro
* remove conditionals for EOLed distribution versions
- Remove gpresagemate, it depends on the long deprecated XEVIE extension
- Set she-bang for /usr/bin/presage_dbus_* to /usr/bin/python2
