Subject: [RFC 8/8] kdbus: Ability to run kdbus test by executable binary name

With this applied, you can do following:

$ cp kdbus-test daemon
$ cp kdbus-test send

Then run 'daemon' in one shell session:

$ ./daemon --bus test

...and 'send' in another:

$ ./send --bus test

Useful for testing features introduced by previous patches.
