[Buildroot] [git commit branch/2019.08.x] package/piglit: set python executable

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=0ce6f87267780aee4fb5c544139303c1cc17295d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.08.x

Without this change, piglit will detect and use python from host
resulting in build failures if python-mako, python-numpy or python-six
are not installed
