pull: Preserve channel ordering when using '--commit', '--url', etc.
Previously using '--url', '--commit', or '--branch' would move the
'guix' channel to the front. This is okay in itself but it gratuitously
leads to a different cache key in 'cached-channel-instance'--IOW, 'guix
time-machine --commit=X' where X is already in cache would gratuitously
recompute the channel derivations.
* guix/scripts/pull.scm (channel-list): Use 'map' instead of 'find' +
'remove' + 'cons'.
