basu: new package

The sd-bus library, extracted from systemd. Some projects
rely on the sd-bus library for DBus support. However not
all systems have systemd or elogind installed. This library
provides just sd-bus (and the busctl utility).

* Fix logging, on NetBSD %m is only allowed in syslog(3) like function
* sendmsg() with a SOL_SOCKET/SCM_CREDS message EINVAL on NetBSD
