meson.build: Fix 'meson dist' on Windows

fanc999-1 · kjellahl · commit 82005b8f65e6 · 2019-12-29T18:11:52.000+01:00
Since we are assured that we are using Python 3.x on when we run Meson, we do not really need to look for the 'python3' executable, but we could just use whatever Python interpreter that is used to run Meson. This will fix situations where it is commonly the case where we may have multiple Python 3.x installations on Windows (www.python.org, and those from Cygwin/mingw-w64), so that Meson really uses one and only one Python installation to run everything that is Python-related, which will thus fix '[meson|ninja] dist' on Visual Studio builds.
