net/remmina: Switch to upstream preferred library selection: webkit2gtk-4.1, libsoup3, libayatana-appindicator

By default remmina grab webkit2gtk-4.1 if installed both webkit2gtk-4.0
and webkit2gtk-4.1. Same for libsoup: 3.0 vs 2.4.
Also remmina prefer devel/libayatana-appindicator instead of
devel/libappindicator as APPINDICATOR.
