Not every image necessarily wants a timestamp file, and even if it
does, it's possible to create filesystem images that do not have a
/etc directory or where some other location for the file is more
appropriate. So add a ROOTFS_TIMESTAMP_FILE variable weakly defaulting
to /etc/timestamp - setting that to the empty string opts out of
creating the timestamp file.
I wasn't sure whether to spell /etc as ${sysconfdir}, but chose /etc
to stay completely backwards compatible.
