bitbake: prserv: make localhost work

After [1] introduced, the PR server doesn't work in docker when use
below setting like before.
PRSERV_HOST = "localhost:0"

And it's because the localhost is resolved to an ipv6 address ::1 as
the below bitbake-prserv shows.
 bitbake$ bitbake-prserv --start --host=localhost --port=42005
 bitbake$ cat prserv.log
    Traceback (most recent call last):
      File "/OE/nodistro/honister/bitbake/bin/bitbake-prserv", line 55, in <module>
        ret = main()
      File "/OE/nodistro/honister/bitbake/bin/bitbake-prserv", line 46, in main
        ret=prserv.serv.start_daemon(options.dbfile, options.host, options.port,os.path.abspath(options.logfile), options.read_only)
      File "/OE/nodistro/honister/bitbake/lib/prserv/serv.py", line 226, in start_daemon
        run_as_daemon(daemon_main, pidfile, os.path.abspath(logfile))
      File "/OE/nodistro/honister/bitbake/lib/prserv/serv.py", line 202, in run_as_daemon
        func()
      File "/OE/nodistro/honister/bitbake/lib/prserv/serv.py", line 224, in daemon_main
        server.serve_forever()
      File "/OE/nodistro/honister/bitbake/lib/bb/asyncrpc/serv.py", line 233, in serve_forever
        self.start()
      File "/OE/nodistro/honister/bitbake/lib/bb/asyncrpc/serv.py", line 144, in start_tcp
        self.server = self.loop.run_until_complete(server_coro)
      File "/usr/lib/python3.8/asyncio/base_events.py", line 616, in run_until_complete
        return future.result()
      File "/usr/lib/python3.8/asyncio/streams.py", line 94, in start_server
        return await loop.create_server(factory, host, port, **kwds)
      File "/usr/lib/python3.8/asyncio/base_events.py", line 1463, in create_server
        raise OSError(err.errno, 'error while attempting '
    OSError: [Errno 99] error while attempting to bind on address ('::1', 42005, 0, 0): cannot assign requested address

So add the extra logic to make the localhost resolved as expected to
make the PR service work especially in docker.
