Don't build full initial logical decoding snapshot if NOEXPORT_SNAPSHOT.

Earlier commits (56e19d938dd14 and 2bef06d5164) make it cheaper to
create a logical slot if not exporting the initial snapshot.  If
NOEXPORT_SNAPSHOT is specified, we can skip the overhead, not just
when creating a slot via sql (which can't export snapshots).  As
NOEXPORT_SNAPSHOT has only recently been introduced, this shouldn't be
backpatched.
