Add support for ARMv6 & ARMv7 builds (for Raspberry Pi)

[mitchellrj]

ARM64 builds are only supported on Raspberry Pi 4 if a non-standard OS image is installed. Any earlier Raspberry Pis, or stock Raspi4s don't have any binaries built for them.

In order to name the output files correctly, there is a bit more customization of the existing goreleaser file than I'd like, but it works well.

@mitchellrj Awesome. I would test it, please meen time sign CLA and then I will rerun check.

Also update please CHANGELOG.md.

The goreleaser on Github is a bit old. Can you update to version: v0.184.0 also to make pass the build phase?

Reproduced the problem with 0.176.0:
