[TestFix] Breakdown sparefile creation into chunkspre_glusterfs_6_0
- Remove decimal before passing to `head` command - Breakup sparsefile into chunks to ~half of brick size - Whole test has to be skipped due to BZ #1339144 Change-Id: I7a9ae25798b442c74248954023dd821c3442f8f9 Signed-off-by: Leela Venkaiah G <lgangava@redhat.com>
