rebase: use rewriteutil.precheck() instead of reimplementing it

After this patch, there's still another place in `rebase.py`, in the
`--stop` code path, that reimplements `rewriteutil.precheck()`. I
couldn't fix that place because it `rewriteutil.precheck()` checks
that there is only one dirstate parent, which fails because we have
two parents at that point. I think it's incorrect that rebase leaves
the user with two parents during conflicts, but changing that is way
out of scope for this series.
