Introduce a shell script that runs in the background and calls
get_overlay to retrive overlays and add them (or remove them) to Linux
device tree (running as a domU).

Besides the same naming issue as in the earlier patch, the script also
looks very Linux-ish. Yet ...
I will fix the naming issue in v2. Would you mind elaborating a bit more
about the "Linux-ish" concern? I guess this is because the original use
case is on Linux, should I do anything about this?

You are right, I think the get-overlay binary and this script should be
installed if DTB overlay is supported. Checking the code, I found
LIBXL_HAVE_DT_OVERLAY which can indicate if we have this feature
supported in libxl. Do you think it is a good idea to use it to install
these two files in Makefile? Thanks.
Kind regards,
