Add support for running Kustomize on Linux ARM64

[ysinjab]

Description

Currently the Kustomize binaries supported only are amd64 on both operating systems Linux and MacOS.

I executed the command uname -a by the repository_ctx.execute to get the current architecture. Based on it either kustomize_v4.5.3_linux_arm64.tar.gz or kustomize_v4.5.3_linux_amd64.tar.gz will be downloaded.
