termios: Suppress clang -Winitializer-overrider on ___cbaud_to_speed 

clang-18 and onwards issues:

../sysdeps/unix/sysv/linux/speed.c:71:23: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
   71 |       [_cbix(__B0)] = 0,
      |                       ^
../sysdeps/unix/sysv/linux/speed.c:70:34: note: previous initialization is here
   70 |       [0 ... _cbix(CBAUDMASK)] = -1,
[...]

The override is explicit used to support the same initialization on
multiple platforms (since the baud values differ on alpha and powerpc).
