Don't print extra parens around expressions in extended stats
The code printing expressions for extended statistics doubled the
parens, producing results like ((a+1)), which is unnecessary and not
consistent with how we print expressions elsewhere.
Fixed by tweaking the code to produce just a single set of parens.
Reported by Mark Dilger, fix by me. Backpatch to 14, where support for
extended statistics on expressions was added.
