0c2b05cbe6 hw/foboot-bitstream: provide yosys/build_template before override. 
Since overridesof the template are done at precise locations (ex: yosys_template[2] += ...),
it's probably better to provide the template in foboot-bitstream. This allow more flexibility
for LiteX's default templates to change/evolve, while also easing foboot-bitstream code understanding.

The override code could also be simplified with the templates provided.

c8872c1088 sw: don't clear OUT buffer during usb_recv 
If there is data already in the OUT buffer, don't throw it away.

This was necessary when using `epfifo` due to the way it shared OUT and
SETUP packets.  However, it is causing reliability issues with eptri.
