py3: re-implement the BaseHTTPServer.test() function

The function is changed in python 3, it does not use sys.argv now,
rather it parses the command line now. So the latest version of function is
re-implemented. One can look at https://hg.python.org/cpython/file/3.5/Lib/http/server.py#l1184
 and https://hg.python.org/cpython/file/2.7/Lib/BaseHTTPServer.py#l590 to see the change.
