setup.c: support multi-checkout repo setup
The repo setup procedure is updated to detect $GIT_DIR/commondir and set $GIT_COMMON_DIR properly. The core.worktree is ignored when $GIT_COMMON_DIR is set. This is because the config file is shared in multi-checkout setup, but checkout directories _are_ different. Making core.worktree effective in all checkouts mean it's back to a single checkout.
