journalctl: make --until work again with --after-cursor and --lines

Fixes a regression introduced by 81fb537.

If one of the cursor option is specified, we first seek to the cursor position.
So, the current position may be out of the time range specified by --until,
and we need to verify the timestamp of the current position.

Fixes #31776.
