            Log:
            use a larger file for mkfs.xfs testing

The automated test used to work with 100MB files. Unfortunately,
the mkfs.xfs program started to complain recently:

  Filesystem must be larger than 300MB.

In order to use the automated test successfully in the future,
the allocated space was increased to 400MB.
