[PATCH v2 1/4] git: pass in repo for RUN_SETUP_GENTLY

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

From: John Cai <johncai86@gmail.com>

commands that have RUN_SETUP_GENTLY potentially need a repository.
Modify the logic in run_builtin() to pass the repository to the builtin
if a builtin has the RUN_SETUP_GENTLY property.
