[PATCH 06/13] xfstests: use command line option for setting extra space

[Dave Chinner <david@xxxxxxxxxxxxx>]

From: Dave Chinner <dchinner@xxxxxxxxxx>

Allow the extra free space to leave in large scratch filesystems to
be specified by a command line option rather than just via an
environment variable.
