py3: conditionalize BaseHTTPServer, SimpleHTTPServer and CGIHTTPServer import
The BaseHTTPServer, SimpleHTTPServer and CGIHTTPServer has been merged into
http.server in python 3. All of them has been merged as util.httpserver to use
in both python 2 and 3. This patch adds a regex to check-code to warn against
the use of BaseHTTPServer. Moreover this patch also includes updates to lower
part of test-check-py3-compat.t which used to remain unchanged.
