Liav A 74a080fb68 LibC: Use proper casting in fgetc and fgetc_unlocked functions ...

In the fgetc function, a fix was already in place but was clunky. A real
proper solution is to use an unsigned char instead of a char when
returning the value, so an implicit cast is happening based on the
assumption that the value is unsigned, so if the variable contained 0xff
it won't be treated as -1, but as unsigned 0xff, so the result int will
be 0xff and not -1.

The same solution is applied to the fgetc_unlocked function as well.
