Merge #20421: build: miniupnpc 2.2.2

180dc3c886 build: miniupnpc 2.2.2 (fanquake)

Pull request description:

  Creating the dll subdir is no-longer required.
  We can drop our wingen patch.

  One issue that came up in [#19867](https://github.com/bitcoin/bitcoin/pull/19867#discussion_r483516359):
  > unrelated to this change but: why are we inserting the architecture in here, seems like something not necessary to reveal

  > My assumption is that it was being inserted to make depends more deterministic. However I think we can improve this, as there's no reason to reveal more of the version information either. Could leave the version as is /2.0 and either drop the architecture, or insert something else?

  I've dropped our `sed` and added a patch that just removes the OS string and miniupnpc version from the User-Agent. i.e:
  ```bash
  # master
  strings depends/x86_64-apple-darwin19.6.0/lib/libminiupnpc.a | rg -i User-Agent
  User-Agent: x86_64-apple-darwin19.6.0, UPnP/1.1, MiniUPnPc/2.0.20180203
  User-Agent: x86_64-apple-darwin19.6.0, UPnP/1.1, MiniUPnPc/2.0.20180203

  # this PR
  strings depends/x86_64-apple-darwin19.6.0/lib/libminiupnpc.a | rg -i User-Agent
  User-Agent: UPnP/1.1
  User-Agent: UPnP/1.1
  ```

  Note that built unmodified (https://github.com/miniupnp/miniupnp/commit/22c13863518adfc4eae11de82cb55a69414afdae), the User-Agent would be:
  ```bash
  strings libminiupnpc.dylib | rg User-Agent
  User-Agent: Darwin/19.6.0, UPnP/1.1, MiniUPnPc/2.2.0
  User-Agent: Darwin/19.6.0, UPnP/1.1, MiniUPnPc/2.2.0
  ```
