etc/scripts/set_copyright_year.sh: Fix exit bug and check LICENSE (#464)

Previously, the `EXIT_CODE` of the copyright year check was hardcoded to
the value 0, causing the CI to pass unconditionally.

This fixes the bug by coupling the `EXIT_CODE` to the result of the
copyright year check. Moreover, the check has been extended to
additionally verify the copyright year of the `LICENSE` file.

This also updates the relevant copyright years that were missed before.

Fixes #458
