Gleb Chesnokov 59bdb2463c scripts/specialize-patch: treat "#if 0" and "#if 0 && ..." as constant-false ...

Partial evaluation can yield guards like "+#if 0 && ...". These are false
but bypassed the filter that only matched exact "+#if 0"/"+#elif 0".
Tighten the regex to match the original spacing and catch both forms.

This is the minimal change addressing the bug observed in logs such as:

  (c) +#if 0 && !(1 && defined(FC_PORTSPEED_256GBIT)) ...
  (g2) ... output = 1   <-- wrong

After this change such guards are dropped correctly (output = 0).
