tests: df-P.sh: fix intermittent false failure

The test writes to the disk and means the space used changes. If this
crosses a number boundary, the heading spacing can change:

-Filesystem     1024-blocks  Used Available Capacity Mounted on
+Filesystem     1024-blocks   Used Available Capacity Mounted on

* tests/df/df-P.sh: Squash spaces with tr to avoid alignment variations.
