Then, let's make syslog_parse_identifier() returns PID as pid_t, rather
than the string.
This also makes the function refuse ridiculously long identifier.
Fixes#40456.
Fixes oss-fuzz#477990732 (https://issues.oss-fuzz.com/issues/477990732).
There isn't really much need to keep them separate. Anything which is a good
corpus entry can be used as a smoke test, and anything which which is a
regression test can just as well be inserted into the corpus.
The only functional difference from this patch (apart from different paths in
output) is that the regression tests are now zipped together with the rest of
the corpus.
$ meson configure build -Dslow-tests=true && ninja -C build test
