RFR: 8346972: Test java/nio/channels/FileChannel/LoopingTruncate.java fails sometimes with IOException: There is not enough space on the disk [v2]

[Volkan Yazıcı]

> Switches from using the temporary directory to work directory in `LoopingTruncate`. This should effectively provide sufficient space for the test finish. Solution is tipped by @bplb. `tier1,2` tests' results will be attached to the ticket once they finish.
