[Buildroot] [git commit] package/gnuradio: fix host python name

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=e0b5ee9f18e79fdf2eb5e7073e32c702bc917c4e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

$(HOST_DIR)/bin/python symlink is only created when BR2_PACKAGE_PYTHON3 is
set.
When only host-python3 is used this symlink is not present and build fails
with:

-- User set python executable buildroot/output/host/bin/python
-- Found PythonInterp: buildroot/output/host/bin/python (Required is at least version "2.7.6")
CMake Error at cmake/Modules/GrPython.cmake:40 (if):
  if given arguments:

    "VERSION_EQUAL" "3"

  Unknown arguments specified
Call Stack (most recent call first):
  CMakeLists.txt:368 (include)

-- Configuring incomplete, errors occurred!

This patch set explicitly PYTHON_EXECUTABLE to $(HOST_DIR)/bin/python3
