Add the RHEL 211.21.1..211.22.1 backports (1288-1351) from centos-stream-10 and
upstream stable, on top of 211.20.1. Bump pkgrelease and specrelease to 211.22.1.
(The redhat/ automotive rebuild-changelog tooling change is omitted: it patches
redhat/scripts not present in this build base and does not affect the kernel.)
