    meson: fix naming/version/path of the .egg-info file
    
    Match what we do with distutils
    
    * Use "PyGObject" as package name (it's not case sensitive, but no need to
      diverge there)
    * Mark unstable releases as dev releases by adjusting the version number
    * Install in the right directory (not the gi package)
