[PATCH] Fix UML on non-standard VM split hosts 



This fixes UML on hosts with non-standard VM splits.  We had changed the
config variable that controls UML behavior on such hosts, but not
propogated the change everywhere.  In particular, the values of STUB_CODE
and STUB_DATA relied on the old variable.

I also reformatted the HOST_VMSPLIT_3G help to make it more standard.
