[OE-core] [PATCH v2 3/4] os-release: add the public package-signing key

[Markus Lehtonen]

Adds the public package-signing key into this package. It will be
installed under /etc/pki/rpm-gpg if the RPM signing feature is used. The
key file is not currently directly used by anything in the target
system. It is merely there for possible later use.

[YOCTO #8134]
