[gtk/1476-nautilus-does-not-enable-to-connect-to-an-nfs-share: 2025/2025] placesview: List only available protocols as available

[António Fernandes <antoniof src gnome org>]

commit d509afd514a36f2ca33151a8a152c4b0fd77075e

    placesview: List only available protocols as available
    
    We display a list of supported protocols in the server_addresses_popover.
    
    However, this curated list contains protocols which may or may not be
    available, depending on the respective gvfs backend being installed.
    
    So, populate the list only with protocols which are available.
