BUG=https://crbug.com/634917

Original issue's description:
> [Mac] Only enable the CFBundleBlocker in the browser process.
>
> In child processes, which are sandboxed in most cases, the sandbox will prevent
> access to the filesystem locations where the potentially blocked bundles are
> stored. Furthermore, on macOS 10.11 and higher, the Google Chrome build is
> codesigned in such a way where bundle loading is blocked by SIP.
>
> This reduces some of the "triggered DYLD shared region unnest for map" messages.
