[libvirt PATCH v2] scripts: Fix meson-install-symlink.py overwriting existing links

By default, symlink re-creation fails if the link already exists, more
specifically in case of meson-install-symlink.py:

Traceback (most recent call last):
  File "/<path_to_libvirt_repo>/scripts/meson-install-symlink.py",
    line 15, in <module>
        os.symlink(target, link)
FileExistsError: File exists: '../default.xml' -> 'default.xml'

Unfortunately, Python can't mimic "ln -sf", so we have to fix this
differently - remove the existing link first and then try re-creating

This version suffers from the same problem as v1, but I didn't bother putting
that into the commit message anymore as the consensus seems to be that we don't
