ARM64 build compatibility

[mickkael]

I've modified all the scripts to allow the build for arm64

[ghost]

All CLA requirements met.

I am also interested in the arm64 release of acr-docker-credential-helper.

I was trying to build with these changes in arm64. I think there are few changes required to make it work on arm64. Please check below for the changes required:

• In build.sh file -

1. At line no. 4 instead of buildGoArch="amd64" we should check the architecture of the platform like -

    if [ "$(uname -m)" == "aarch64" ]
    then
       buildGoArch="arm64"
    else
       buildGoArch="amd64"
    fi
   

2. At Line no.-14 instead of “docker run --name ${buildContainerName} ${buildImageName}” it should be “docker run --name ${buildContainerName} -e GOARCH=$buildGoArch ${buildImageName}”

• In DOCKERFILE at line no. 1 we should replace “FROM golang:1.8-alpine” with “FROM golang:1.14-alpine” as golang:1.8-alpine image is not available for arm64.

After these changes, the binary for arm64 was created successfully. So, I think it will be good to add the small changes mentioned above to make it in arm64.

Actually I launch the build by providing GOARCH as a parameter, and it works without any issue. But yes your modification would make it nicer. I'll test and update
