NFD cluster-nfd-operator make image support for arm64 deployment from github repo needs Dockerfile updates

For arm64 OCP 4.12 cluster, running `make image` from https://github.com/openshift/cluster-nfd-operator.git to build the NFD operator image from master branch fails.  Need to update Dockerfile otherwise the following error is generated:

[1/2] STEP 4/4: RUN make build exec /bin/sh: exec format error Error: error building at STEP "RUN make build": error while running runtime: exit status 1

Dockerfile updates needed:
