Add missing 'expires' field to VirtualTestSuites
Add missing 'expires' field to VirtualTestSuites

The upstream Chromium CL https://crrev.com/c/4039561 added a new
field "expires". This is currently missing and causing our
CQ/CI runs to fail.

Instead of reverting this CL adds the missing field, which needs
to happen anyway.
