Fix docker-ce repo for ARM64

Docker-ce apt repository used armhf (32bit) architecture tag
instead of correct arm64.
Remove "edge" repo channel enforcement for Ubuntu 18.04 and ARM as it
is not necessary. Both 32bit and 64bit ARM binaries of docker-ce
are available in the stable repo channel.
Adding spaces around variable names to avoid ansible lint issue [206].
