channels: Key cached channel derivations by system. 

Previously, the channel instance to derivation mapping would be
independent of the system.  Thus, building the same channel instance for
several different systems would always return the derivation that was
first computed.

This is a followup to c3ab921eed.

* guix/channels.scm (channel-instance-derivations)[instance->derivation]:
Pass the current system as a third argument to 'mcached'.
