[singlejar] Various portability fixes for MSVC

- MSVC does not have `errx` functions, so use `diag_errx` etc. instead.
- Fix format when trying to print `size_t`, use `%zu` so that the function will handle 32/64-bit `size_t` according to target system automatically.
- Adding/guarding a few includes for MSVC.
- MSVC does not have `ssize_t`, so replace it with `ptrdiff_t`
