scripts/unifdef: avoid constexpr keyword

Browse Source 
Starting with c23, 'constexpr' is a keyword in C like in C++ and cannot
be used as an identifier:

scripts/unifdef.c:206:25: error: 'constexpr' can only be used in variable declarations
  206 | static bool             constexpr;              /* constant #if expression */
      |                         ^
scripts/unifdef.c:880:13: error: expected identifier or '('
  880 |                 constexpr = false;
      |                           ^

Rename this instance to allow changing to C23 at some point in the future.
