menuconfig: Fix crash when toggling symbols without a type

Trying to toggle the following symbol crashed the menuconfig:

  config FOO
  	prompt "foo"

Symbols defined without a type are pointless and generate a warning
(particular definition locations can omit the type, but some definition
location should give a type if the symbol is defined in multiple
locations). We should never crash for them though.

Fix the crash. The code assumed that the symbol's current value would
appear in Symbol.assignable, like for a visible bool/tristate, but
symbols without types get their name as their value.

Also skip printing "(NEW)" next to symbols without a type.
