Don't spuriously report FD_SETSIZE exhaustion on Windows. Starting on 2023-08-03, this intermittently terminated a "pgbench -C" test in CI. It could affect a high-client-count "pgbench" without "-C". While parallel reindexdb and vacuumdb reach the same problematic check, sufficient client count and/or connection turnover is less plausible for them. Given the lack of examples from the buildfarm or from manual builds, reproducing this must entail rare operating system configurations. Also correct the associated error message, which was wrong for non-Windows. Back-patch to v12, where the pgbench check first appeared. While v11 vacuumdb has the problematic check, reaching it with typical vacuumdb usage is implausible.
