Resolves: https://issues.redhat.com/browse/RHEL-124989
Upstream: kdump-utils
Conflict: none
Fixes three situations where kdump can fail by,
- adding "KeyringMode=shared" to the kdump.service unit file so it can access the LUKS volume keys
- fixing the SELinux label of crypttab file
- allowing users to use "sudo kdumpctl"
