Adjusts test expectations for AlmaLinux 10 and Rocky Linux 9 to account
for alphabetical ordering of release files. When /etc is listable,
almalinux-release is found before centos-release, but when /etc is not
listable (TestOverallWithEtcNotReadable), centos-release is found first
due to the distro library's probing order. Rocky Linux 9 similarly finds
centos-release before rocky-release in both scenarios.

Adds override of test_almalinux10_release in TestOverallWithEtcNotReadable
to test the different behavior when /etc is not listable.
