If a cold reboot occurs in the middle of patch installation, the
system can be left in a state where the patch-agent is unable to
perform its operations properly. The RPM database can be left with
duplicate RPMs due to the incomplete transaction, which can in turn
lead to DNF update installation issues.
This update adds detection of duplicate RPMs to the patch-agent to
avoid attempting installation until the system is recovered.
Additionally, protection is added to the sw-patch init to treat
multiple reboot patch installations as an error, to avoid boot loops.
