Fix a regression in APPEND type derivation.

Do not just test the arguments for validity by being subtypes or
supertypes of LIST, but also if it's a subytpe of NULL, since ATOM or
SYMBOL won't satisfy the LIST tests.

Regression since f32ee7d.."Better type derivation for APPEND, NCONC,
LIST.", reported by Eric Marsden.
