[PATCH] licenses: add GPL-2.0-with-Linux-syscall-note

According to Linux copying notice[^1] the SPDX copyright should be
`GPL-2.0 WITH Linux-syscall-note`.
AFAIK there is no `WITH` operator in yocto yet, so I created
GPL-2.0-with-Linux-syscall-note based on SPDX[^2] and Linux[^3].
spdx.org/licenses does not list this license, because of the prefered use of
WITH operator.
For example GPL-2.0-with-autoconf-exception[^4] is now marked deprecated.

It would be good to have something like `LICENSE = "GPL2.0-only +
Linux-syscall-note"`
in the future.

+ Also note that the GPL below is copyrighted by the Free Software

+ kernel) is copyrighted by me and others who actually wrote it.

+ Also note that the only valid version of the GPL as far as the kernel

+ v2.2 or v3.x or whatever), unless explicitly otherwise stated.
