Subject: Make /run/lock tmpfs an API fs
The /run/lock directory is world-writable in Debian due to historic
reasons. To avoid user processes filling up /run, we mount a separate
tmpfs for /run/lock. As this directory needs to be available during
early boot, we make it an API fs.
Drop it from tmpfiles.d/legacy.conf to not clobber the permissions.
Closes: #751392
