Switch to the real MIT license

Due to a copy/paste error, the COPYING file and subsequently created files
with the same content referred to the "Historical Permission Notice and
Disclaimer - sell variant", not the proper MIT license.

Replace with the proper MIT (Expat) license and add the use SPDX license
identifiers.
