darwin-install: fix already-mounted store volumes

This adds an explicit unmount of the store volume to avoid cases
where the installer can hang in await_volume when:
- the user already has a store volume
- that volume is already mounted somewhere other than /nix
- they do not take a path through the installer that results in an
  explicit unmount (as both removing and encrypting the volume
  would do)
