Python packages used to install the RBTools entrypoint as

Scripts\rbt-script.py, which was a Python script that ran

rbtools.__main__(). This changed at least as of our last release. The

modern tooling instead installed that as rbt.exe.
These are exe files that run themselves as Python scripts, so we can

still link to them. They are, unfortunately, installed using

non-relocatable paths to the Python executable, so we can't include them

directly in the path. However, we fortunately can continue to pass them

to python as scripts, and it'll do the right thing.
Our rbt and rbt.cmd files have been updated to wrap these instead of

the old path.

Installed these on Windows and verified I could successfully run rbt.
