Backport v2023<-v2024dev1: Fix journalctl cursor use

Backport !19 (merged) and !20 (merged)

Using --after-cursor in combination with -t audit does produces the expected output since the filtering logic is applied before and after that the cursor is moved to next valid entry. In this case, using --after-cursor will cause the output to miss the first entry in the log.

To fix it save the cursor also taking into account the type of entry we are interested on, so later when we use it we can safetly check entries with --after-crusor.
