Allow "reposync" to filter packages using the entire NEVRA (bsc#1234226)

[meaksh]

What does this PR change?

This PR enables spacewalk-repo-sync to filter packages matching the entire "NEVRA" instead of the package name only.

This extended nevra filtering must be enabled in rhn.conf by setting:

server.satellite.reposync_nevra_filter = 1

This is particularly useful when dealing with big repositories, where package name filters are not enough and you want to use more fine-grained filters to synchronize only certain packages.

Before this PR:

# spacewalk-repo-sync -t deb -c testchannel-deb -u https://packages.gitlab.com/gitlab/gitlab-ee/ubuntu/dists/noble/main/binary-amd64/ -i gitlab-ee_17.1.0*
[...]
14:36:57 Repo URL: https://packages.gitlab.com/gitlab/gitlab-ee/ubuntu/dists/noble/main/binary-amd64/
14:36:57     Packages in repo:                45
14:36:57     Packages passed filter rules:     0
[...]
