vcu128/vcu128_system_constr: Enable internal diff term for Ethernet clock 

There are no external termination resistors on the VCU118 and VCU128 for
the SGMII clock lines.
The board files of the VCU118 enables them, but this was not reflected in the
constraint files.

For VCU128 the clocking is similar, even if diff terms are not set in the
board files we should have a consistent approach with the VCU118.
