build: Make sure configure uses configure.ac mtime.

Since we moved the rsync into the container, configure dependency on
configure.ac was broken, leading to it not being regenerated until a
second build. This is because timestamps are read by make earlier than
the rsync, which runs after the top-level rules are checked.
