Joachim Wiberg 127049d925 test: Finit against a real dbus-daemon
The other dbus-*.sh tests drive libink's own client, so the wire format
was only ever checked against the implementation that wrote it, and the
broker path had no coverage at all.  Every bug found in it so far was
found by hand on a target.

Let the dbus plugin bring up a real dbus-daemon, wait for Finit to
claim org.finit, then talk to Finit with dbus-send, which shares no
code with us.  The privileged call is the interesting one: it can only
be answered by parking the call and asking the broker who sent it.
The bus reads the policy Finit installs, so a malformed org.finit.conf
fails here rather than on a target.

Tests no longer build --with-libsystemd.  Our replacement carries the
real soname but only the sd_notify() symbols, so in the test root it
shadowed the libsystemd the host's libdbus-1 wants and dbus-daemon
died on a missing sd_is_socket.  Nothing under test needs the shared
library: serv is the only consumer and it compiles sd-daemon.c
straight in, which it now does regardless of the flag so notify.sh
keeps testing notify:systemd either way.

Staged from the host by lib/sysroot.mk like any other binary, and
skipped when the host has neither program.

<!--
The system bus configuration for the test namespace, deliberately
permissive. It lives where a stock system bus daemon looks for its
configuration, so the dbus plugin's own invocation finds it.
What is under test is Finit attaching to a broker and serving calls
routed through it, not dbus policy, so nothing here should be able
to refuse a message and make a Finit bug look like a policy denial.
Everything runs as root inside the namespace, hence no <user>.
