set SO_KEEPALIVE on control connection

Attempt to prevent timeouts of the control connection by setting SO_KEEPALIVE.
This matches the equivalent behaviour in ftpd.

Note: This is a much simpler change than adding a background polling event
to invoke "STAT" (or "NOOP") on the control connection during a transfer.
(It's unclear from RFC 959 whether "NOOP" is even permitted during a transfer).
