LibC: Make WEOF a signed value on clang

The actual value is unchanged, but the previous `0xffffffff` was an unsigned value, which lead to clang getting mad at `foowc() == WEOF`. This commit makes it a signed int on clang, which *should* serve the same purpose and not lead to clang getting mad at us.
