mkosi: Update to latest

- ACLs are not set on generated directories anymore by default, so
we enable them explictly now so that when running unprivileged mkosi,
the user running mkosi can remove all generated files and directories.
- We don't explicitly set QemuHeadless= anymore as the option was removed
and made the default.
- We set the loglevel= kernel cmdline argument explicitly now as mkosi
doesn't set it by default anymore.
