Revert "Roll reclient, buildtools; update related DEPS to match Chromium"

This reverts commit 2110deada3fe7fef7a1855c0fa30d9ddd8b9de6a.

Reason for revert: Still causing a bunch of mac flakes. Seems to be an issue with running reclient on mac11; may try using siso's own remoteexec instead of reclient.

Original change's description:
> Roll reclient, buildtools; update related DEPS to match Chromium
>
> This reverts commit c875dc549dc48b2a560b574d15035fe0af0ad00f
> and adds speculative fixes. The issue seemed to be related to
> buildtools, so roll buildtools to version from chromium 'main', and also
> update download_and_configure_reclient_cfgs to match Chromium 'main', at
> the same version I took the reclient release number from.
