[PATCH 6/6] src/uapi/wireguard: add SPDX tag

[Greg Kroah-Hartman]

It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.

Update the wireguard.h file with the currently convential GPL2+userspace
exception tag.

Note, this is a different license than what the text itself says in the
file, if you wish to stick with the MIT license for this file, that's
fine, but then it should be listed as:
	((GPL-2.0 WITH Linux-syscall-note) OR MIT)
