Subject: liveupdate: remove liveupdate_test_unregister()
Date: Fri, 27 Mar 2026 03:33:32 +0000

Now that file handler unregistration automatically unregisters all
associated file handlers (FLBs), the liveupdate_test_unregister() function
is no longer needed.  Remove it along with its usages and declarations.
