dont use cmake 3.10 .deb, it reserves Python3::Interpreter
dont use cmake 3.10 .deb, it reserves Python3::Interpreter

Summary:
cmake 3.10 on ubuntu 18.04 reserves the Python3::Interpreter target so that the FBPythonBinary.cmake rules can't definite it when missing

This breaks builds using the Python3::Interpreter rule, notably the python-six manifest which in turn is used by fbthrift

The fix is to use the getdeps manifest cmake manifest instead on .deb platforms.  Once CI is on ubuntu 20.04 everywhere we could revisit
