Split the libs into their own subpackage

Some applications, like GNOME Builder, require the devhelp libs.

This allows installing them without dragging in the Devhelp app as a
dependency.

Note that the libs subpackage needs to include the translation files,
and the gsettings, as per the upstream maintainer's recommandation.
