deps: upgrade to libuv 1.38.0

Notable changes:

- `uv_library_shutdown()` has been added.
- `uv_udp_init_ex()` now accepts `UV_UDP_RECVMMSG`, although it
  is a no-op.
- Obsolete `MAX_PATH` restrictions have been removed on Windows,
  and Windows is now long path aware.
- Windows environment variables longer than 32,767 characters are
  now supported.
- Linux `cpu_times` are now reported as milliseconds to match
  other platforms.
- A memory leak resulting from `uv_loop_init()` failures has
  been fixed.
