Log Message:
Add omniidl_be_init hack.

Both the omniORB package and py-omniORBpy install files into
${PYSITELIB}/omniidl_be, but the only files that conflicts are __init__.py
with the comment "Empty file to convince Python that this is a module."
and __init__.pyc.
So if this package is being built with the same PYTHON_VERSION_DEFAULT as
omniORB was simply don't install the __int__.py{,c} files.
