Clear MAKEFLAGS when running dvsim.py

Browse source 
dvsim.py runs make as a subprocess, which gets rather confused if
MAKEFLAGS appears in its environment. The proper fix is to clear them
from the environment in the dvsim command: we'll do that on the
OpenTitan side[1] and can revert this patch once that change is vendored
in.
