Look for config in /usr as well

[DaanDeMeyer]

The UAPI group is trying to work towards working image-based Linux systems that contain only /usr (see uapi-group/specifications#76). To make this work it'd be great if rpm-sequoia would look for its policy in /usr/share/crypto-policies if the environment variables aren't set and no config file is found in /etc/crypto-policies

Sorry for not responding. In #72, I've changed rpm-sequoia to first look for the crypto policy in /etc/crypto-policies/back-ends/rpm-sequoia.config, and if that does not exist, /usr/share/crypto-policies/back-ends/rpm-sequoia.config.

@nwalfield I just took a look and on Fedora the rpm-sequoia default config in /usr is shipped in a different location /usr/share/crypto-policies/back-ends/DEFAULT/rpm-sequoia.config . Any chance rpm-sequoia could look there?

@DaanDeMeyer: I don't know anything about this. It would be good if we did the right thing and not just changed paths randomly. Could you please find out what the officially sanctioned way to find the correct location is and follow up here? Thanks!
