[PATCH v2 13/25] setup_bare_git_dir(): help static analysis

[Johannes Schindelin]

Coverity reported a memory leak in this function. However, it can only
be called once, as setup_git_directory() changes global state and hence
is not reentrant.

Mark the variable as static to indicate that this is a singleton.
