Enable DownloadRequestManager for Mac.

DownloadRequestManager is the object that manages the number of downloads
that can occur in a given tab. It throttles non-user initiated downloads
to prevent carpet-bombing download attacks.

Enabling this object for Mac fixes the issue where we can only download
one file in a given tab.

BUG=None (mac work).
TEST=Can now download more than one item in a tab.
