depends: build miniupnpc with CMake
Summary:
This picks up one of the changes from #29232, which is a switch to building miniupnpc with CMake. It includes an update to the most recent version of miniupnpc (2.2.7), which means we can drop one patch from that commit, and includes a new patch for a change I've upstreamed miniupnp/miniupnp#721, as well as some suggestions from the previous PR.
Backport of core#29707.
Depends on D16567.
Test Plan: Run the GUIX builds.
