[libgweather] build: Bump soname

[Bastien Nocera <hadess src gnome org>]

    build: Bump soname
    
    Bump the soname after the GWEATHER_LOCATION_ADM2 enum member removal
    in commit 4e7a3a9. This changes the values of the enum member after
    it, and can cause crashes in applications that weren't rebuilt against
    the 3.32 version.
    
    Closes: #17
