CVE-2022-4415: systemd: coredump not respecting fs.suid_dumpable kernel setting
Affects systemd >= 247 with libacl support enabled.

This is a merge of https://github.com/systemd/systemd-security/pull/12/.
I'm doing the merge locally because github doesn't support merging directly
from systemd/systemd-security to systemd/systemd.
