PATCH 1/1 mkreiserfs: set the owner of the root directory to the calling user

Hi,

Following patch sets the owner of the root directory to the calling user.

This is also how mke2fs behaves. It enables users to e.g. create a file system on removeable storage devices and then be able to actually use them.
