[PATCH v2 6/7] run-command: declare the `git_shell_path()` function globally

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The intention is to use it in `git var GIT_SHELL_PATH`, therefore we
need this function to stop being file-local only.
