Switch from temporary sigslot.h to the right one.

This CL switch only imported header file to unblock WebRTC refactoring
to move sigslot target to proper location. But it is required that
all usages of sigslot will be eliminated from chromium code base. Here
is a ticket to track this effort: https://crbug.com/867820
