[OE-core] [PATCHv5 3/8] kernel-artifact-names.bbclass: use PR instead of PKGR in KERNEL_ARTIFACT_NAME

[Martin Jansa]

* otherwise PKGR seen in do_install, do_deploy and do_deploy_links will
  have different value in each of them (PRSERV will return different
  value of EXTENDPRAUTO because TASKHASH is different for each of these
  tasks and also cause unnecessary multiple EXTENDPRAUTO increments for
  each build).

[YOCTO #12937]
