[PATCH] mkinitcpio: mount real root device instead of symlink

[Dave Reisner <d@xxxxxxxxxxxxxx>]

If a symlink such as /dev/disk/by-uuid/xxxxx is provided on the kernel cmdline,
resolve it and mount that device instead of the symlink.  This prevents some
ugliness in the output of commands such as mount or df.
