Relicense hwdb/parse_hwdb.py as MIT (#4129)

This parser will also be used in libinput, which uses the MIT license, so
relicense this file to the more permissive license to make bidirectional code
flow easier. parse_hwdb.py is only useful during building of the project, and
is not part of the installation, so effectively both licenses are very similar.
In particular, the licensing of binary packages produced by systemd is not
influenced in any way, because the MIT licensed part is not installed.
