Pepper: Allow Compositor and VideoDecode on dev channel.

Pepper: Allow Compositor and VideoDecode on dev channel.

An earlier change to narrow the whitelisting behavior for the Compositor and
VideoDecode APIs enforced whitelisting, but removed the channel version check
which permits use of these API on dev and canary builds of Chrome.

This fixes that regression (and highlights the need for better testing for API
permissions).
