util/u_printf: Fix const correctness in util_printf_next_spec_pos

Browse source 
Fix compiler error:

../src/util/u_printf.c:75:13: error: initializing 'char *' with an
expression of type 'const char *' discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
   75 |       char *spec_pos = strpbrk(str_found, "cdieEfFgGaAosuxXp%");
      |             ^          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

glibc now provides C23-style type-generic string functions. strpbrk
returns const char * when passed a const char * argument. Update
spec_pos declaration to match.
