Subject: [PATCH] tests: fix raid0 tests for 0.90 metadata

Some of the test cases fail because raid0 creation fails with the error,
"0.90 metadata does not support layouts for RAID0" added by commit,
329dfc28debb. Fix some of the test cases by switching from raid0 to
linear level for 0.9 metadata where possible.
