Fix E0308 to compile on apple hardware

`S_IWUSR` is of type `mode_t`: https://github.com/rust-lang/libc/blob/d80e8bd3056d82fec80c022819084bdb0be3bdaa/src/unix/bsd/apple/mod.rs#L2928 On apple, `mode_t` is u16 https://github.com/rust-lang/libc/blob/d80e8bd3056d82fec80c022819084bdb0be3bdaa/src/unix/bsd/apple/mod.rs#L11 On linux, `mode_t` is u32 https://github.com/rust-lang/libc/blob/d80e8bd3056d82fec80c022819084bdb0be3bdaa/src/unix/linux_like/linux/mod.rs#L6
