Fix: Vim scripts loaded on Unix systems, when git config --global core.autocrlf, fail to load

[JL102]

Fixes #1025 (See note: #1025 (comment))

Added the config option git.override_autocrlf, with a default of true, which forces config.autocrlf=false when cloning repos. Tested on Windows and Ubuntu.

To verify:

1. Set git config --global core.autocrlf true
2. nvim -u repro.lua repro.lua
3. Since override_autocrlf was not overridden and the default is true, neo_tree loads without error on both Windows and Linux. Note that .repro/plugins/neo_tree.nvim/plugin/neo-tree.vim has LF line endings.
4. rm -rf .repro
5. Modify repro.lua and remove the comment around override_autocrlf = false
6. nvim -u repro.lua repro.lua
7. On Linux, neo-tree will fail to load. On Windows, neo-tree will load fine. Note that .repro/plugins/neo_tree.nvim/plugin/neo-tree.vim has CRLF line endings.

Thanks!

I just pushed a change to always set that option. Thanks!
