Add a script to buildtools to report the minimum meson version given in
our meson.build file. Then use this script in two ways:
1. in the .ci/linux-setup.sh script, use the auto-determined minimum
version to set up the CI, rather than hard-coding it.
2. in meson.build call the script to report the version. This serves as
a sanity check to ensure that any changes to meson.build file do not
break the script.
