handy.h: Set macro to false if can't ever be true

It's unlikely that perl will be compiled with out the LC_CTYPE locale
category being enabled.  But if it isn't, there is no sense in having
per-interpreter variables for various conditions in it, and no sense
having code that tests those variables.

This commit changes a macro to always yield 'false' when this is
disabled, adds a new similar macro, and changes some occurrences that
test for a variable to use the macros instead of the variables.  That
way the compiler knows these to conditions can never be true.
