When exiting PID 1 we most likely don't have stdio/stdout open, so the final LSan check would not print any actionable information and would just crash PID 1 leading up to a kernel panic, which is a bit annoying. Let's instead attempt to open /dev/console, and if we succeed redirect LSan's report there. The result is a bit messy, as it's slightly interleaved with the kernel panic, but it's definitely better than not having the stack trace at all: [ OK ] Reached target final.target. [ OK ] Finished systemd-poweroff.service.

All other usages of sd_varlink_call* do not free the json return parameter, and it is owned by the varlink object instead. Do the same here.
