Remove messages about not being able to uninstall packages from /prog/res/komodo

[pinkwah]

Pip install does:

1. Install package into the user's komodoenv
2. Try to remove the old package

Well, if the package is installed into /prog/res/komodo proper then it won't be able to remove the package due to correctly missing permissions.

It's weird that it tries at all. This issue should be considered resolved if any of these are done:

1. We patch pip so that it doesn't try to do anything with /prog/res/komodo at all
2. We patch pip so that it doesn't output warnings about not having permissions
