Add TestBuildWCOWSandboxSize integration test

Browse source 
This test validates that `RUN` and `COPY` both target a read-write
sandbox on Windows that is configured according to the daemon's
`storage-opts` setting.

Sadly, this is a slow test, so we need to bump the timeout to 60 minutes
from the default of 10 minutes.
