Relicense the leftover GPL-2.0-only files

The relicensing can be done because the Atmosphère-NX upstream has the
following license addition:

"""
The yuzu Nintendo Switch emulator and the Ryujinx Team and Contributors are
exempt from GPLv2 licensing. They are permitted, each at their individual
discretion, to instead license any source code authored for the Atmosphère
project as either GPLv2 or later or the MIT license. In doing so, they may
alter, supplement, or entirely remove the copyright notice for each file
they choose to relicense. Neither the Atmosphère project nor its individual
contributors shall assert their moral rights against any of the
aforementioned projects.
"""
