v7a: run: really constrain the forwarded SSH port to <= 64000
The variable expansion braces should have been arithmetic evaluation
parentheses, which had the effect that the PPID was always used as a
port number (which incidentally works fine for PPIDs < 65535).
Fixes: d975eb8b04087f8606d8 (2021-04-26, "v7a: run: make the SSH forwarding port multiprocess-compatible")
