supply: Fix harmless bug in supply from ship in same sector

Bug bites when a ship supplies the sector it's in.  First the sector
is charged zero mob for moving the stuff, and is written back.  Next,
the sector receives the stuff, and is written back, clobbering the
first write (no effect), and triggering a seqno oops.

accept: Drop outdated FIXME SO_KEEPALIVE

SO_KEEPALIVE isn't useless with long idle timeouts.  Before v4.3.30's
idle timeout changes, such long timeouts had serious drawbacks (easy
denial of service), but they're just fine since then.
