Vladimir Sementsov-Ogievskiy 819cec0114 iotest 055: refactor and speed up
Source disk is created and filled with test data before each test case.
Instead initialize it once for the whole unit.

Test disk filling patterns are merged into one pattern.

Also TestSetSpeed used different image_len for source and target (by
mistake) - this is automatically fixed here.
