Junio C Hamano a6c7a27691 rebase -i: correctly remember --root flag across --continue
d911d14 (rebase -i: learn to rebase root commit, 2009-01-02) tried to
remember the --root flag across a merge conflict in a broken way.
Introduce a flag file $DOTEST/rebase-root to fix and clarify.

While at it, also make sure $UPSTREAM is always initialized to guard
against existing values in the environment.
