[master][PATCH 2/2] rootfs-postcommands.bbclass: add post func remove_unused_dnf_log_lock

[<changqing.li@windriver.com>]

From: Changqing Li <changqing.li@windriver.com>

Remove log_lock.pid which maybe created during do_rootfs. In commit
[dnf: only write the log lock to root for native dnf],
native dnf changed to write log lock to root, and target dnf still
use /var/log, so log_lock.pid need to be removed post do_rootfs.
