[ptxdist] [PATCH v2 1/2] rauc: fix license and add license files checksums

[Roland Hieber <rhi@pengutronix.de>]

Until recently, RAUC's license was only given implicitly in the
meson.build file. Backport the unreleased upstream patch making the
license explicit, so we can pin down that information with a checksum.

The license identifier was previously ported from "LGPL-2.1" to
"LGPL-2.1-only" in PTXdist commit 4850f7aac30aebf4ef64 (2018-02-12,
Michael Olbrich: "update all spdx license identifier to the new
version") without adding any license file checksum as source, which
turned out to be slightly incorrect. Fix the identifier based on the
newly added patch.

+Subject: [PATCH] README: clarify license
+
+Simply including the LGPL license text is not enough information to
+determine the license of a software project, as Section 13 of the LGPL
+allows licensees to choose the terms of "any later version of the
+license" if specified so by the copyright holders.
+
+The information in meson.build implies "LGPL-2.1-or-later" as project
+license. As a minimal measure to make this information explicit, add the
+usual license notice and warranty disclaimer as recommended in the GNU
+GPL How-To to the README file, and also add a minimal copyright notice
+as required by Section 1 of the LGPL.
+
+Let the LGPL badge at the start of the README point to the relevant
+section further down.
