ceph.spec: declare PyYAML and Jinja2 Requires for cephadm RPM

cephadm's zipapp imports yaml and jinja2. When the package is built
with cephadm_bundling and RPM-sourced deps (--without cephadm_pip_deps),
only BuildRequires were listed for jinja2 and no runtime Requires were
declared for PyYAML or Jinja2, so minimal "dnf install cephadm" could
fail with ModuleNotFoundError. The unbundled cephadm case also lacked
PyYAML.

Add matching BuildRequires/Requires in the rpm-bundle branch and
Requires (plus SUSE naming for Jinja2/PyYAML) in the no-bundle branch.
