Version check for arm images

[Virsacer]

When checking the image-version on a raspberry pi it does not work:

root@RASPI2 ~ $ docker pull pihole/pihole
Using default tag: latest
latest: Pulling from pihole/pihole
Digest: sha256:abdddfb266ddd8e0591f97203ad11fd8dc33f2542187223f20ff18862b76bfbb

root@RASPI2 ~ $
root@RASPI2 ~ $ /etc/nagios/check_docker.py --version
CRITICAL: PiHole's version does not match registry
root@RASPI2 ~ $

When I do the same on a amd64 system it shows different image-id and works without problems:

root@Ubuntu ~ $ docker pull pihole/pihole

latest: Pulling from pihole/pihole

Hi @timdaman
I can confirm this. I also get a crit alarm on my raspi although I have the latest image.
