nix-channels: Tolerate new release taglines 

The release tagline format changed and now has timezone and Git commit
information. Try to be more tolerant to those.

Old .released-time files may have already been collected with incorrect
data. Handle those as well.

See https://github.com/NixOS/nixos-channel-scripts/pull/99
