This reverts commit b74f2d2d1c.
Reason: the merging was done to please the license detection library
underlying pkg.go.dev. Since pkg.go.dev treats dual licensed projects
as the intersection ("AND") of the licenses, and because the UNLICENSE
is not supported per
https://pkg.go.dev/license-policy
revert to the usual once-license-per-file.

Apparently github.com/google/licenseclassifier/tools/identify_license
doesn't like that LICENSE is missing.
Merging the two separate license files makes one less file, and by adding the
SPDX identifier at the top I believe there is even less ambiguity that Gio
is covered by the UNLICENSE as well as the MIT license, as described in
the README.md file.
