AppVeyor related updates

- Disable 2.7 tests. Too much to bite off at this point...and since 2.7 is deprecated it may not matter
- Update conda-build to version 3.17 and build local activate_deactivate_package
- Retain line endings on bat files in the activate_deactivate_package
- Simplify path adjustment logic in activate_deactivate_package batch files. (This may be unnecessary as controlling the line endings may have fixed the issue)
- Update condarc tests to write files without duplicate keys.
