tizen: Enable udev synchronisation

Formatting a device-mapper device sometimes generates an udev event and
sometimes not. It seems to be a race condition between udev rules processing
and device-mapper (once the device node is created both are modifying it
simultaneously). The option --enable-udev_sync enables synchronisation between
device-mapper and udev. After applying this commit the race condition was not
observed.
