Require image for ARM64 architecture

[odidev]

Hi team,
I am trying to use swce/metadata-resource on ARM64 architecture but it seems the arm64 tag is not available in Docker Hub.
I tried to build it using the command docker build -t <image_name> . on arm64 platform but it is not building successfully on arm64.

I have made the below changes to resolve errors and build the image successfully.

I have used Travis-CI to build and push the image for both platforms.
