[Buildroot] [git commit branch/2019.08.x] package/ninja: invoke python3 explicitly to configure the package

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a1400dd65ca942785a6a8c1daed2acb0f23f7287
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.08.x

ninja depends on python3 specifically, but the configure.py file
simply uses "env python". Where no python is selected for the target
you simply won't get a python symlink in $(HOST_DIR)/usr/bin, so the
configure.py script fails to run since it can't find "python".

Notice that in order to reproduce the issue, you must not have
python2 installed on your host machine.
