    Replace hardcoded krb5.conf with use of GSS-Proxy
    
    Instead of having our own krb5.conf and pulling in the kerberos ccache
    from the user environemnt inside the flatpak runtime, let's use
    GSS-Proxy instead. GSS-Proxy's proxymech.so plugin intercepts GSSAPI
    calls and forwards them to the gssproxy service. By bind-mounting the
    gssproxy service socket in the flatpak environment, we outsource
    dealing with all the kerberos configuration and ticket management to
    the host user session.
    
    As a bonus we avoid exposing the kerberos tickets to the flatpak
    environment.
