Merge bitcoin#25964: build: fix mingw miniupnpc cflags

859644b build: set D_WIN32_WINNT=0x0601 for mingw miniupnpc (fanquake)
8e2d93f build: fix cflags passing for mingw miniupnpc (fanquake)

Pull request description:

  Pulls in a patch I've upstreamed to miniupnpc so that we properly pass our cflags when building it for mingw. See miniupnp/miniupnp#619. Also set `D_WIN32_WINNT` to `0x0601` to match libevent, configure etc. Previously it was being set to `0X501`.
