testbenches/ip/spi_engine: update test_program and test_slowdata

Both tests were not generic regarding the sdi_lane_mask. They were
relying on the default value, which is not guaranteed that it is
going to enable all lanes.
Added instructions to change the sdi_lane_mask before executing the
tests for the FIFO and Offload modes.
