The dtschema package must be somewhat up to date as the tools and
meta-schema checks are still evolving. Implement a version check,
so this can be enforced. This will help ensure new schema submissions
get checked against the latest meta-schemas.

v3:
- Drop leading '0' in version month
- Rework with Masahiro's shell commands
v2:
- Use a build rule for the version check instead
