sd-bus: derive uid from cgroup if possible
Whenever we run in a user context, sd_bus_{default_user,open_user}() and
friends should always connect to the user-bus of the current context,
instead of deriving the uid from getuid(). This allows us running
programs via sudo/su, without the nasty side-effect of accidentally
connecting to the root user-bus.
This patch enforces the idea of making su/sudo *not* opening sessions by
default. That is, all they do is raising privileges, but keeping
everything set as before. You can still use su/sudo to open real sessions
by requesting a login-session (or loading pam_systemd otherwise).
However, in this case XDG_RUNTIME_DIR= will not be set (as usual in these
cases), hence, you will not be able to connect to *any* user-bus.
Long story short: With this patch applied, both:
- ./busctl --user
- sudo ./busctl --user
..will successfully connect to the user-bus of the local user.
Fixes #390.
