Richard Maw 8799346862 test: mount overlayfs over /usr in some tests
Most of the integration tests have been made to not write to /usr
but some genuinely need to do so.

Because mkosi creates images with a read-only /usr
it is not normally writeable.

By mounting an overlayfs with /usr as the lower dir
and upper and working dirs in /var tests may write to /usr.
