How to ignore LD_LIBRARY_PATH

[Orion Poplawski]

See https://bugzilla.redhat.com/show_bug.cgi?id=719785 for the motivation

The environment module system allows users to modify their environment in a 
predictable way, including setting LD_LIBRARY_PATH.  However, this makes it 
possible to break the modulecmd binary by putting an incompatible TCL (or 
other) library earlier in the path.  It would be great if modulecmd were made 
impervious to such things, but I don't know the best or acceptable method to 
do this.  I'm guessing using rpaths would be the easiest.

Thoughts/suggestions?
