Get run_exports the slow way

[duncanmmacleod]

channeldata.json only contains one run_exports entry for each version of each package; some packages (looking at you fftw) have multiple builds of the same version with different run_exports. This PR naively undoes some recent work to force recipe rendering to use the slow, but robust method of accessing run_exports.

I'm not sure if this PR is well-motivated, or if there is a better solution to the run_exports problem, so I haven't added news entries, but will do if this change is acceptable.

I don't think that's the right solution. We should fix channeldata.json - it sounds like it is broken. Can you add a test with your fftw package and your desired output from channeldata.json?

[msarahan]

I think this is fixed in #3611 - closing. I think we may need the build string differentiator as discussed on gitter, though.

Variants are not fixed by #3611
