LibC: Add fseeko/ftello
This changes the signatures for FILE::seek and FILE::tell, to use `off_t` as they use lseek internally. `fpos_t` is also redefined to use `off_t`. Dr. POSIX says that fpos_t is: > A non-array type containing all information needed to specify uniquely > every position within a file. In practice, most *NIX typedef it to `off_t`, or a struct containing an `off_t` and some internal state.
