test: test journalctl with corrupted journals
Last month I monkey-patched journald to produce a small (64K) but valid
journal and used that as an input to four AFL fuzzers. After a month it
generated quite a nice corpora (4738 test cases) and after filtering
and minimizing it I was left with 619 unique journals with various
levels of corruption that probe the journal code.
It seems to detect past issues like systemd#26567, etc.
