scons.py - misorders extra_args to dfu-util

[benagricola]

Trying to program a pico-ice using apio upload, triggering dfu-util and receiving the following error:

(base) ➜  fpga git:(main) ✗ apio upload

dfu-util -d 1209:b1c0 -a 0 -D --reset hardware.bin
Error: Unexpected argument: hardware.bin
Usage: dfu-util [options] ...

This is because the --reset argument is inserted between the -D arg and the build file.

My quick fix for this locally was to put the extra_args block above the args block but I don't know if this would cause issues with other programmers.
