Fix crash when evaluating "(signal nil 5)" (bug#78738)

The docstring already warns against calling signal with a nil
error symbol, which is for internal use only, but we can avoid crashing
in this case.

* src/eval.c (Fsignal): Produce a "peculiar error" for more arguments
involving non-lists.

(cherry picked from commit 888f846d377a589c6fca5be5d2f4274f423e5fcf)
