arm: Rework "cannot carry nukes" test for robustness

Browse source 
We reject satellites, ABMs, anti-ship missiles, and SAMs.  That's
enumerating badness.  More robust replacement: accept only bomber,
tactical, cargo, except for anti-ship missiles.

Throw in PLN_LAUNCHED sanity checking while there.
