Unix-domain socket address can be long enough that the NUL terminator does not fit. Handle this case by making `path()` return a `Cow<CStr>` and adding a NUL terminator as needed. Also add a `path_bytes()` function for returning the raw bytes. Fixes #1316.

Would it maybe be possible to make the array one element longer instead? |

We define |
Using `.to_owned()` + `.push()` will cause a reallocation, because the initially allocated array with be one byte too short. We can use `CString::from_vec_with_nul_unchecked()` because it is a known invariant that the input does not contain any `NUL`s, not even the terminating `NUL`.
