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 require extra work/maintenance so we will implement it only if required.
