meson: Improve detection of Python when using Meson >=0.50.

Previously, on systems where multiple versions of Python 3 (e.g. 3.6 and 3.7)
are installed, wrong version of Python 3 could have been used.

The proper fix requires availability of path() method in Meson's python
module, which has been added in Meson 0.50:
