mkfs.ubifs: Add support for symlinks in device table
It is not possible to change ownership for symlinks in the device table file.
This patch adds support for symlinks equal to mkfs.jffs2 and updates the
sample device table file. The permission entry for symlinks in the device
table must be set to 0777.
