linux: add support for driver 615.71.09

[jailuthra]

Possibly fixes #1120

[dsummer]

Tested on RTX 5070 (Blackwell), Debian 13, driver 615.71.09. NVENC patch works; the NvFBC entry does not.

patch.sh works but patch-fbc.sh not working....

From #1120

@dsummer Hmm I can't seem to find the function in the latest driver whose retval we were bypassing in previous patches.

Can you check if NvFBC works for you without the patch?

@forumi0721 could you please verify if NvFBC works for you without the patch?

NvFBC doesn't work for me without the patch. I got it working with this bytecode.
