Remove reltarget_has_non_vars flag.

Commit b12fd41c added a "reltarget_has_non_vars" field to RelOptInfo,
but failed to maintain it accurately.  Since its only purpose was to skip
calls to has_parallel_hazard() in the simple case where a rel's targetlist
is all Vars, and that call is really pretty cheap in that case anyway, it
seems like this is just a case of premature optimization.  Let's drop the
flag and do the calls unconditionally until it's proven that we need more
smarts here.
