[Jordan Petridis <jpetridis src gnome org>]

commit bc77763e1d1f9a57075ad639d36f863ee040846c
Author: Sven Neumann <sven svenfoo org>
Date:   Fri Oct 23 16:00:11 2020 +0200

    rework the debian build
    
    * Remove obselete ubuntu and i386 builds
    * Move the scripts inline the dockerfile
    * rename the dockerfile so syntax highliting in editors works
    * add openssl to the builddeps
    * remove ccache from the deps as its no longer used
    
    * Export GDK_PIXBUF_QUERYLOADERS var so autotools doesn't complain
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907306
    
    * build the image with a usernamespace by default so it
    works with our unpriv gitlab runners
    similar to c19a8634d51985288c77ad491693f4c62bba6f95
