Pepper: Send dev/canary channel status to plugins.

As part of supporting "dev channel" methods in Pepper APIs, the plugin needs to
know whether or not it's running in a channel that supports those methods.

This patch plumbs that information through LoadPlugin so it's available by the
time get_interface<>() would ever be called.
