With https://github.com/systemd/mkosi/pull/630, we can set environment
variables for the build script in mkosi. Let's modify the build script
so we can set the version-tag option via an environment variable of the
same name. The default is the empty string which causes meson to fall
back to the default behavior (git version).
-D man=false \
-D "nobody-user=$nobody_user" \
-D "nobody-group=$nobody_group" \
- -D translations=false
+ -D translations=false \
+ -D version-tag="${VERSION_TAG}"
