Create a dedicated fastrpc group and add the qcom user to it. This grants unprivileged access to FastRPC device nodes needed for DSP offload.

Looks good. Ideally we should have an adequate mechanism in place to add / configure the usr/groups, that does not require touching the build_rootfs tool at all. I'll add that to the list of issues I am tracking.
