Fixes serial interrupt enabling on x86 hardware

Qemu didn't need the bit set, but our desktops (16550(A)s) do.  Nice to
know that my old IO Ports list called that bit "auxiliary
user-designated output 2".  My bad for clobbering that bit (that was on
by default) when attempting to set the flow control.
