Some core system frameworks were refactored in iOS 9. Although the various system sandboxes were updated, the WebKit sandbox was missed, resulting in spurious SandboxViolation errors. We should allow this communication channel.

The network process needs access to the UTI information cached in com.apple.lsd.mapdb. We hit sandbox violations for these requests frequently in NetworkProcess, which is a needless performance bottleneck.
