multi-arch image

[duckman]

I was excited to see arm64 added but when I pull k8s.gcr.io/node-problem-detector/node-problem-detector:v0.8.9 I still get standard_init_linux.go:228: exec user process caused: exec format error

[nvtkaszpir]

I can confirm this, on rpi4 I get amd64 linux image:

docker inspect k8s.gcr.io/node-problem-detector/node-problem-detector:v0.8.9

[nvtkaszpir]

the image itself is still ELF 64-bit LSB executable, ARM aarch64, not executable on rpi.
doing extra target with GOARM=6 GOARCH=arm CGO_ENABLED=0 will generate working binaries (but it requires ENABLE_JOURNALD=0 though)

[Random-Liu]

We only built multi-arch binaries, but not docker images.

Please feel free to add multi-arch image support into the Makefile, I can help review the change. :)
