Fix deb packaging for ARM v6/v7

Relates to goreleaser/goreleaser#2721

There's a filename clash because some platforms consider `armhf` to be ARMv6 and some consider it to be ARMv7. Fallback to build and package only ARMv6 because ARMv6 binaries are going to work on ARMv7 anyway.

Note: If we really have to release ARMv7 for other platforms, we can split the builds and packaging and then filter the builds used for packaging but that requires extra work/maintenance so we will implement it only if required.
