[network-manager-openconnect] Drop libsecret-unstable fallback

[Thomas Haller <thaller src gnome org>]

    Drop libsecret-unstable fallback
    
    Most of the libsecret API was declared stable in 0.18.
    This happened in 2014, over 3 years ago, so the fallback to
    libsecret-unstable is no longer necessary.
