rasperry-pi zero (armv6l) support

[tristan-k]

I tried to run your docker-image on a raspberry pi zero but it keeps restarting over and over again. This seems related to the report made here, here and here. Is there something you can do to make the image compatible with a raspberry pi zero?

@tristan-k It's been a very long while but this morning I compiled a linux/arm/v6-image. If you want you could try it out: https://hub.docker.com/r/pluim003/pihole-unbound/tags (it's in the nightly-build and uses the pihole-docker nightly build with Unbound 1.16.3.

Note, I found also out that the arm/v7-image didn't work on my 'old' Pi2 with Debian stretch and Linux-kernel 4.9.something. Upgraded this one also to bullseye and the latest Linux kernel 5.15-70 and everything is working fine. It also did though with kernel 5.10 if I'm not mistaken. But guess bullseye must be a prerequisite.
