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 unchaged.
