chore: update some missed files to new MIT license (#920)

While working on a DEP-5 machine readable copyright file for the Debian
packages, I noticed that the SPDX tag differs from the actual license
text.

The license text in question is identical to the
[NTP](https://spdx.org/licenses/NTP.html) license, not
[MIT](https://spdx.org/licenses/MIT.html).
