Source disk is created and filled with test data before each test case.
Instead initialize it once for the whole unit.

performance:
qcow2: 25s -> 15s
  raw: 16s -> 11s

Actually, changed only TestSetSpeed: before this patch it used different
image_len and data pattern.
Alse TestSetSpeed used different image_len for source and target (by
mistake) - this is automatically fixed here.
