leveldb: Allow to build with CMake 4+

Browse Source 
The component itself builds just fine with CMake 4, but the tests don't as they
rely on a bundled version of GTest that is six years old. Since upstream is
inactive, the simplest course of action is to apply the 'minimum policy version'
override (as implemented in CMake, it only affects the GTest submodule).

System GTest can not be used instead (easily), as among other things it requires
C++14 and the project uses C++11.
