deps: upgrade to libuv 1.32.0

Notable changes:

- `uv_tcp_close_reset()` has been added.
- `uv_udp_set_source_membership()` has been added.
- A double free in `uv_free_cpu_info()` on OpenBSD
  has been fixed.
- Defined, but empty environment variables can now
  be read on Windows.
- Several improvements to the cmake build process.
- The `EILSEQ` error code is now mapped by libuv.
