scripts/unifdef: avoid constexpr keyword
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.
