Install sandcastle dependencies as RPMs (#2114)

Install sandcastle dependencies as RPMs

Trying to workaround failing reverse-dep-packit-service-tests in packit:
packit_service/worker/helpers/build/build_helper.py:10: in <module>
    from kubernetes.client.rest import ApiException
/usr/local/lib/python3.9/site-packages/kubernetes/__init__.py:20: in <module>
    import kubernetes.config
/usr/local/lib/python3.9/site-packages/kubernetes/config/__init__.py:17: in <module>
    from .kube_config import (list_kube_config_contexts, load_kube_config,
/usr/local/lib/python3.9/site-packages/kubernetes/config/kube_config.py:33: in <module>
    from requests_oauthlib import OAuth2Session
/usr/local/lib/python3.9/site-packages/requests_oauthlib/__init__.py:4: in <module>
    from .oauth1_session import OAuth1Session
/usr/local/lib/python3.9/site-packages/requests_oauthlib/oauth1_session.py:12: in <module>
    from oauthlib.oauth1 import SIGNATURE_HMAC, SIGNATURE_RSA, SIGNATURE_TYPE_AUTH_HEADER
E   ImportError: cannot import name 'SIGNATURE_RSA' from 'oauthlib.oauth1' (/usr/lib/python3.9/site-packages/oauthlib/oauth1/__init__.py)

I don't know what's going on there (I haven't been able to reproduce), but the /usr/local/lib/python3.9 vs. /usr/lib/python3.9 looks suspicious to me.
