channels: Add mechanism to patch checkouts of the 'guix channel.
* guix/channels.scm (<patch>): New record type. (apply-patches): New procedure. (latest-channel-instance)[dot-git?]: New procedure. Use 'update-cached-checkout' and 'add-to-store' instead of 'latest-repository-commit'. Call 'apply-patches' when CHANNEL is the 'guix channel. (%patches): New variable. * guix/git.scm (url+commit->name): Make public. * tests/channels.scm ("latest-channel-instances includes channel dependencies") ("latest-channel-instances excludes duplicate channel dependencies"): Mock 'update-cached-checkout' instead of 'latest-repository-commit'. Wrap body in 'with-store' and pass the store to 'latest-channel-instances'.
