bitbake: add a new option "--server-only"

Create a new option "--server-only" for bitbake command, which allows
bitbake runs as a server, and let frontend connect the server itself.

"--server-only" should work with "-t xmlrpc", or bitbake will exit.

bitbake --server-only -t xmlrpc will print out the server address and
port information.
