[TCLCORE] Some tests require Internet access

[Reinhard M. <rei...@m4...>]

Hi,

while preparing the SUSE RPMs for Tcl9 I came across some tests which 
break in restricted build environments that have no internet access for 
security reasons. More specifically some of the httpProxy tests try to 
access www.google.com and fail like this:

---- Test generated error; Return code was: 1
---- Return code should have been one of: 0 2
---- errorInfo: couldn't open socket: Temporary failure in name 
resolution
     while executing
"http::geturl http://www.google.com/"

I think depending on the intention of these tests they should either 
have a constraint that skips them when there is no internet 
connectivity, or they should use a local dummy web server instead of 
reaching out to google.
