Linux build instructions for AEO light (with thanks to @znerol)

Instructions are written as a Dockerfile to facilitate testing. Use docker cp in order to retrieve the binary after a successful build. Note that in order to actually run the binary on other machines it is necessary to install the required runtime libraries (i.e., libtiff, qt5 including the multimedia component and ffmpeg). Also it is necessary to also retrieve /usr/local/lib/libDSPFilters.so from the image, since that one is not linked statically.
