[PATCH] xfstests: Improve test 219 to work with different filesystems

[Jan Kara <jack@suse.cz>]

Different filesystems account different amount of metadata in quota. Thus it is
impractical to check for a particular amount of space occupied by a file
because there is no right value. Change the test to verify whether the amount
of space is between the expected amount of space and the expected amount +5%.
The number of files is checked exactly as previously.

 Dave, does this look better?
