Pad and align the callout_cpu mtx to its own cacheline to reduce false
sharing especially on the default CPU 0 callout_cpu structure.

This will be followed up by attilio@ with a conversion to the new struct
mtx_padalign but doing this manual conversion first gives an easy MFC
candidate since mtx_padalign is a more extensive system change.
