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.

A service that drops privileges cannot create its own PID file in
/run, root owns it. Finit can create the file with pidfile-create,
but the daemon still cannot touch it to confirm a SIGHUP.
Five new settings, block format only: runtime-dir, state-dir,
cache-dir, logs-dir, and config-dir. The value is a directory name,
resolved under /run, /var/lib, /var/cache, /var/log, and /etc,
respectively. The directory is created before the service starts,
mode 0755 owned by user/group, and the full path is exported to the
process as RUNTIME_DIRECTORY, STATE_DIRECTORY, CACHE_DIRECTORY,
LOGS_DIRECTORY, and CONFIGURATION_DIRECTORY. Mode and ownership are
asserted at creation only, a daemon may tighten them afterwards.
The runtime directory is removed when the unit stops, after any
exec-stop-post script, like systemd with RuntimeDirectoryPreserve=no.
A completed run/task counts as stopped unless remain-after-exit keeps
it up. The other four persist across restarts.
These are the first settings with no legacy token: they are validated
by service_set_dir() and stored on the svc that service_register()
now returns. systemd accepts a list of directories per setting; this
is a single name for now, widening later is compatible since
libconfuse accepts a bare value for a list option.
The test sysroot gains libnss_files.so.2, which ldd cannot see, glibc
dlopen()s it. Without it getpwnam() fails inside the chroot, so
user/group settings never resolved and directory ownership could not
be tested.

Then it works to run the applets from outside the unshare. Useful for
testing and test development.
