PATCH: move processing of -V|--version to earlier point

[Jacob Bachmeyer]

This patch moves the processing for "runtest --version" to the first run 
through the command line arguments.  Since the presence of this option 
completely alters program flow, leading to an early exit rather than 
running tests, there is no reason to load the rest of the framework just 
to print version numbers from runtest.exp itself, the Expect extension, 
and the Tcl interpreter.  The latter two preclude moving this processing 
to the "runtest" shell script, since the Tcl and Expect versions are 
from the Expect interpreter running the main runtest.exp module.
