Use feels_like_helping() in dosupport(), lnd_support()

Browse source 
feels_like_helping() case cn == foe is missing in the code it
replaces.  No difference in behavior, because:

* cn == foe && cn == friend can't happen.  Because you can't get into
  ground combat against yourself (assault, attack and paradrop don't
  let you), friend != foe for support.

* cn == foe && cn != friend behaves the same: no support.
  feels_like_helping() returns 0 because of the explicit case.  The
  replaced code doesn't support because cn can't be at war with
  itself.
