test/py: Drop u_boot_ prefix on test files
We know this is U-Boot so the prefix serves no purpose other than to make things longer and harder to read. Drop it and rename the files. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Mattijs Korpershoek <mkorpershoek@baylibre.com> # test_android / test_dfu
