The existing GCONV_PATH set in the mcopy wrapper doens't work with the updated 
uninative directory layout. It also means that it might not work correctly in 
the
native case when uninative is not in use.

Tweak uninative to set GCONV_PATH into the environment for everything to
avoid these problems. Refactoring the code in uninative into a function 
is beneficial at this point.

Based on a patch from Randy Witt.
