sysdig: Allow to build with CMake 4+

The latest release seems to have support to build with CMake 4+, but updating
requires major changes to the recipe and so far I haven't managed to get a build
passing. Thus, apply the 'minimum policy version' override instead and backport
one patch to unblock builds with CMake 4.
