Fix bitwise-and build issues on macOS
I was seeing build errors due to attempting to bitwise-and a u32 and a u16:
```
error[E0308]: mismatched types
--> src/util/unix.rs:6:50
|
6 | LIBC_PERMISSION_VALS.iter().any(|val| mode & *val != 0)
| ^^^^ expected `u32`, found `u16`
error[E0277]: no implementation for `u32 & u16`
--> src/util/unix.rs:6:48
|
6 | LIBC_PERMISSION_VALS.iter().any(|val| mode & *val != 0)
| ^ no implementation for `u32 & u16`
|
= help: the trait `std::ops::BitAnd<u16>` is not implemented for `u32`
```
I fixed this by simply up-converting `*val` to a `u32`.
The widening won't have any effect on functionality because we don't care about any of the higher bits.
