Kai Lueke fff345a944 coreos-base/update_engine: Fix opaque directory handling
When /etc way kept busy through, e.g., a process using it as CWD, then
even in the temporary namespace unmounting failed unless it was done
with the lazy option.
This pulls in https://github.com/flatcar/update_engine/pull/52 to
address this.
