ssci: canonicalize / backfill dependencies managed by DEPS

A LSC to canonicalize and backfill "Version: N/A; Revision: DEPS"
if the dependency managed by the readme file has non-compliant versioning information, and can be plausibly identified as "managed by DEPS".

This is the first step to fix "insufficient versioning information" at
scale, as it allows us to tell "managed by DEPS" apart from "genuinely
missing versioning information".
