se.py Ruby: Connect TLB walker ports

In order to ensure correct functionality of switch CPUs, the TLB walker ports
must be connected to the Ruby system in x86 simulation.

This fixes x86 assertion failures that the TLB walker ports are not connected
during the CPU switch process.

se.py --ruby checkpointing and restore in timing CPU.  Will need to be tested again when restoring into detailed CPU is working with Ruby.
