man page updates
The first patch upstreams the generic portions of https://github.com/oracle/solaris-userland/blob/60ead572067e5fe89f8f3a8226ae712cfaf5b2c8/components/desktop/dbus-glib/patches/dbus-glib-02-manpage.patch with some tweaks to make it more generic (@PACKAGE_STRING@ instead of Solaris 11.4, @bindir@ instead of our bindir, etc.)
The second patch takes the notice from the README file and adds it to the the man page with some added text to point people in the right direction for that particular tool.
