ti-rtos: Update path for firmwares on j7200
ti-rtos: Update path for firmwares on j7200

Between j7200 firmware tags 07.03.00.10 to 07.03.00.16
the downloadable weburl link changed
from *processor-sdk-rtos-jacinto7 to *processor-sdk-rtos-j7200.

This patch is to fix the recipe to pick the firmware from the
expected location on the new tag.

Fixes j7200 build error reported due to
77cdfa9f6560 ("ti-rtos: Update metadata and versions for RTOS firmware")
