contrib/fedora: add --meson option to build_clean
Summary
This merge request adds a --meson option to the build_clean.sh
script, which lets you use Meson throughout the entire build process.
Purpose
Since we are working towards deprecating/removing Autotools, we need to make sure that we can use meson as a replacement for every single step where autotools is currently used.
