git has started rejecting repositories owned by other users and refusing to run the "git rev-parse HEAD" command in this type of cases. That resulted in issues with the VM testing model where the VM is practically running everything as root while the host is a normal development environment and likely a non-root user owned files. Fix this by fetching the commitid on the host and pass it to the VM so that no git operations need to be run within the VM itself. Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
