The Zynq driver in the FPGA Manager framework on Linux expects bitstreams that are byte swapped with respect to what the Vivado command `write_bitstream -bin_file` produces. Thus, use the `write_cfgmem` command with appropriate options to generate the bitstream (.bin file). Fixes amaranth-lang#519.
