The bridge, and also some parts of pkg/lib/ are GPL-3.0-and-later
licensed, not LGPL-2.1. At some point we should clean this up, but for
now accept the status quo and ship the GPL 3 text.
The four patternfly react-templates copies in pkg/lib are MIT licensed.
Rename/add them to "LICENSES/<spdx>.txt" as recommended by
https://reuse.software/spec-2.0/
Note: pkg/storaged/icons/gnome-icons.jsx is CC-BY-SA-3.0 licensed (or
LGPL-3.0). This does not have a canonical plaintext format, just the
webpage. So don't copy that, retaining the current license header in
that file is good enough.
Adjust the .spec accordingly.
