website: blow away $JIRI_ROOT in setup instructions

Necessary because bootstrap.sh expects $JIRI_ROOT to not
already exist.

Our Jenkins test harness currently does not start each test
from a clean slate/workspace, so it's necessary to manually
blow away old unwanted state. (It would be better if the
default was a clean slate, with a whitelist for state that
should persist across tests.)
