Thinking more about this, other restrictions could theoretically also
be >1. Since I'm not sure we'll actually be encountering such
installers, I think we currently go with this API and when we actually
encounter such an installer, we:

1. Allow multiple avatar formats, i-e add a
osinfo_install_script_get_avatar_formats()
2. Make _get_avatar_format() return the first restriction in the list
3. Document in _get_avatar_format() about #2 and that apps should use
the new API
