Options for zfs storage driver were incorrectly placed
under 'exec driver options' header. Move the header to
the correct place.

DeviceMapper must be explicitly selected because the Docker binary might not be linked to the right devmapper library.
With this change, Docker fails fast if the driver detection finds the devicemapper directory but the driver is not the default option.
The option `override_udev_sync_check` doesn't make sense anymore, since the user must be explicit to select devicemapper, so it's being removed.
Docker fails to use devicemapper only if Docker has been built statically unless the option was explicit.
