sd-event: always reshuffle time prioq on changing online/offline statev248.6
Before 81107b8419c39f726fd2805517a5b9faab204e59, the compare functions
for the latest or earliest prioq did not handle ratelimited flag.
So, it was ok to not reshuffle the time prioq when changing the flag.
But now, those two compare functions also compare the source is
ratelimited or not. So, it is necessary to reshuffle the time prioq
after changing the ratelimited flag.
Hopefully fixes #19903.
(cherry picked from commit 2115b9b6629eeba7bc9f42f757f38205febb1cb7)
Hopefully fixes #20285 and
