stdio: Fix -Wtautological-constant-out-of-range-compare on clang
clang emits an error while building vfprintf-internal for default
case:
error: result of comparison of constant 255 with expression of type
'char' is always true
[-Werror,-Wtautological-constant-out-of-range-compare]
if (spec <= UCHAR_MAX
The test is indeed not required for default non-wide build.
