upm: Undefine PYTHON_EXECUTABLE cmake variable

upm has its own mechanism to detect python that it has inherited from
openCV, this was forked long time ago and never updated to latest from
openCV, ideally it should be fixed to entertain PYTHON_EXECUTABLE
variable passed from cmake but it does not and causes build errors,
proper fix is left for upm community, here we ensure that we can still
compile after OE-Core change
