package/python-setuptools-rust: add host setuptools-scm dependency

We need host-python-setuptools-scm for python-setuptools-rust to build
correctly when using a pep517 frontend.

Fixes:
* Getting build dependencies for wheel...
running egg_info
writing setuptools_rust.egg-info/PKG-INFO
writing dependency_links to setuptools_rust.egg-info/dependency_links.txt
writing entry points to setuptools_rust.egg-info/entry_points.txt
writing requirements to setuptools_rust.egg-info/requires.txt
writing top-level names to setuptools_rust.egg-info/top_level.txt
reading manifest file 'setuptools_rust.egg-info/SOURCES.txt'
reading manifest template 'MANIFEST.in'
adding license file 'LICENSE'
writing manifest file 'setuptools_rust.egg-info/SOURCES.txt'
