[net] Increase HostCache size to 1000 entries on CrOS.
The built-in async DNS client notoriously fills up the small (100-entry) cache.
To even out the playfield for the field trial, drastically increase the size.
This is a temporary measure before we can tune the size according to performance.
BUG=114277
TEST=on CrOS, check HostCache size in chrome://net-internals/#dns
