Fix gitignore so ripgrep works

ripgrep was failing to search in the bindgen repo: ``` ./.gitignore: line 19: error parsing glob '**.orig': invalid use of **; must be one path component ``` Per the gitignore docs it seems like ripgrep is correct and this line is invalid: https://git-scm.com/docs/gitignore#_pattern_format
