It's only the name that suggested this, it could've been a
`ci/build_script.sh`, I just used the name because it, of course,
reminded me of the old ways.

Basically the whole point of this is to have the line:

   meson build --werror $MESON_OPTS || (cat build/meson-logs/meson-log.txt && exit 1)

only written in one place, and possibly similarly with some ninja
invocations.  It would be almost exclusively used by the CI, although it
could be also useful for some people.
