Revert of roll_dep: Avoid large commit messages by providing the log as a link (patchset #1 id:1 of https://codereview.chromium.org/1257233006/ )

Reason for revert:
Blink merge is done, blink people won't have to use it anymore.

Original issue's description:
> roll_dep: Avoid large commit messages by providing the log as a link
> 
> The majority of chromium projects are on googlesource.com, which can
> display a range of commits on the web. Use this feature instead of
> dumping logs into the commit message.
> 
> Particularly, this avoids creating large commit messages as these logs
> sometimes contain upwards of 50 commits.
>
