As part of moving all python iotest invocations of qemu-img onto a
single qemu_img() implementation, remove a few lingering uses of
qemu_img_pipe() from outside of iotests.py itself.

Several cases here rely on the knowledge that qemu_img_pipe() suppresses
*all* output on a successful case when the command being issued is
'create'.

065: This call's output is inspected, but it appears as if it's expected
      to succeed. Replace this call with the checked qemu_img() variant
      instead to get better diagnostics if/when qemu-img itself fails.

237: "create" call output isn't actually logged. Use qemu_img_create()
      instead, which checks the return code. Remove the empty lines from
      the test output.

296: Two calls;
      -create: Expected to succeed. Like other create calls, the output
               isn't actually logged.  Switch to a checked variant
               (qemu_img_create) instead. The output for this test is
               a mixture of both test styles, so actually replace the
               blank line for readability.
      -amend:  This is expected to fail. Log the output.

After this patch, the only uses of qemu_img_pipe are internal to
iotests.py and will be removed in subsequent patches.
