[net] Increase HostCache size to 1000 entries on CrOS.

[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

File net/base/host_cache.cc (right):

net/base/host_cache.cc:81: static const size_t kMaxHostCacheEntries = 100;
nit: static on these data items seems like a waste.  I hope the compiler gets
rid of this variable... but static might possibly confuse the issue.
