analyze: use normal bus connection for "plot" verb (#7685)

We need to connect to hostnamed, so a private bus connection is no good.
It'd be simpler to use the normal bus connection unconditionally, but
that'd mean that e.g. systemd-analyze set-log-level might not work in
emergency mode. So let's keep trying to use the private connection except
for "plot".

Fixes #7667.
