Closes#60.
Resolves the malformed-patch issue from #61 (since reverted in #62)
by regenerating the 0003 patch via actual application against firefox
150.0.3 Pi-OS source.
Functional change vs prior 0003: walking hw_configs accepts
AV_HWDEVICE_TYPE_DRM (legacy) OR integer device_type values 13/14
(AV_HWDEVICE_TYPE_V4L2REQUEST in Kwibos no-AMF / upstream-AMF trees).
CreateV4L2RequestDeviceContext passes integer 13 (Kwibos value) cast
to enum AVHWDeviceType for the av_hwdevice_ctx_create call.
Tested: applied cleanly via patch -p1 against firefox-150.0.3 source
post-Pi-OS-quilt-patches. Test build follow-up in firefox-rpios EC2
script (drops the in-source sed hack from v7-v8).
