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.
