docker: images optimisation:
- reduced the number of layers by grouping many instructions
- moved stuff which don't change a lot at the beginning, and hg/apt at the end
- scripts are not now in scripts/ subdirectories
- prosody.cfg.lua is added using ADD instead of getting it online
- .hg/dirstate is copied in base (backend) and libervia, so mercurial revision is known
- removed lot of useless WORKDIR instruction, they are replaced by "cd" inside RUN instructions
- cleaning (apt-clean, rm) is done on the same instruction as the one than generate the data, to avoid useless data in layers
