    Documents Flatpak: Build liboauth against NSS
    
    Currently available versions of liboauth, such as 1.0.3, don't build
    against OpenSSL 1.1.0, and that has been failing the nightly builds.
    It does work with NSS, though; and, for what it's worth, Fedora builds
    liboauth against NSS too.
