download_and_map.py: write "no enough space" warning message to network log file

If there is no enough space left in the disk, download_and_map.py will refuse to download any data.

This can be quite mysterious for a maintainer.

So, write the reason to the network log file.

The reason is something like:

"[download_and_map.py] home directory does not have enough space (only 13 G available)."
