The idea is that 'read-channel-metadata' will take care of converting
possibly older versions to the current data type.  Thus, storing the
version number is unnecessary.

* guix/channels.scm (<channel-metadata>)[version]: Remove.
(read-channel-metadata, channel-instance-dependencies): Adjust
accordingly.
