when rotating the system journal file due to corruption, log that fact to the journal once we are done with it, not just kmsg

[cmurf]

systemd version the issue has been seen with

systemd-245.4-1.fc32.x86_64

Expected behaviour you didn't see

This kernel message should be in the systemd-journal also.

$ dmesg | grep corrupt
[    4.989946] systemd-journald[566]: File /var/log/journal/2d2b0efcba8442caaf742548b8b2e6ef/system.journal corrupted or uncleanly shut down, renaming and replacing.
$ 

Unexpected behaviour you saw

Journal corruption message is not in the journal.

$ sudo journalctl -b | grep corrupt
