Roll Syzygy deps.

Version 0.8.0.0

As of this version, SyzyASan has been entirely refactored and much of it
reimplemented. New mechanisms exist for finding bugs in external/uninstrumented
code, and coverage has been increased.

This version also marks the official separation of Syzygy from Sawbuck, it's
original ancestor. Syzygy is now hosted in a pure GIT repository, and built with
Ninja.

Some highlights:

[4e6b4f9b19] Refactor of zap_timestamp.
[a01d2374e6] SyzyASan - Zebra heap fully implemented.
[990009f460] SyzyASan - Large block heap fully implemented.
[735e51eb5c] SyzyASan - Narrowed crash race conditions as much as possible.
[08ebb870d9] Full Ninja support for the build.
[45d2fb0bec] SyzyASan - CTMalloc support added.
[217fe21486] Fully split from Sawbuck repository.

It failed because the get_syzygy_binaries script is still depending on
includes.zip and libs.zip, which aren't part of our build anymore. This is fixed
by https://codereview.chromium.org/662543009/
