Remove libsoup2 support

Three libraries (librest, libgeocode and libgweather) still used
libsoup-2, although they already support being compiled with
libsoup-3. Since mixing both versions when linking binaries is
not possible (and, in fact, an specific check is done at runtime
to abort the execution if that case is detected), I think that is
time to remove the old one.

This PR entirely removes libsoup-2 library and recompiles those
three libraries using libsoup-3.
