Prevents:
setuptools.errors.InvalidConfigError: No configuration found for dynamic 'license'.
Seems to be OK to do because not only does
$TERMUX_PREFIX/lib/python3.12/site-packages/vapoursynth-0.0.0.dist-info/licenses/COPYING.LESSER
still appear, but also Termux still adds
$TERMUX_PREFIX/share/doc/vapoursynth/copyright
to the package anyway
