std: fix aliasing bug in UNIX process implementation
`CStringArray` contained both `CString`s and their pointers. Unfortunately, since `CString` uses `Box`, moving the `CString`s into the `Vec` can (under stacked borrows) invalidate the pointer to the string, meaning the resulting `Vec<*const c_char>` was, from an opsem perspective, unusable. This PR removes removes the `Vec<CString>` from `CStringArray`, instead recreating the `CString`/`CStr` from the pointers when necessary. Also,`CStringArray` is now used for the process args as well, the old implementation was suffering from the same kind of bug.
