Define conda channel names in environment file

[ewels]

Docker builds are failing because the conda solving environment takes too long. Could be worth specifying the channel for each package to try to speed this up.

eg. bioconda::multiqc=1.7 instead of just multiqc=1.7

It's not just the docker builds, also running the pipeline with the conda profile fails because it takes too long to create the environment.

I just tested pinning the channels, it doesn't really help, building the environment still takes ages. I will do some further testing with a more recent conda build and the recommendations here:

bioconda/bioconda-recipes#13774

By the way, do we still need the fastqc specific workaround after bioconda/bioconda-recipes#12616 was merged?

I think I found the culprit, it's the channel priorites. Pinning the channels however makes it slow again.. very confusing.

Thanks for looking in to this!
