actions: register qemu with capability binfmt flag

problem: Arm64 container build still running into issues even avoiding
sudo in the docker container, it's hiding in check run, Debian-based
distributions by default register binfmt_misc loaders without support
for setuid propagating into the container

solution: This adds the `--credential` argument to the script in the
container, and strips out the github actions indirection so we can
maintain it.  This should change the flags from F to OC or OCF, either
should allow the setuid of the sudo binary to be preserved
