path.c: Use vsnpath() in the implementation of git_path()
The current implementation of git_path() is essentially the same as
that of vsnpath(), with two minor differences. First, git_path()
currently insists that the git directory path is no longer than
PATH_MAX-100 characters in length. However, vsnpath() does not
attempt this arbitrary 100 character reservation for the remaining
path components. Second, vsnpath() uses the "is_dir_sep()" macro,
rather than comparing directly to '/', to determine if the git_dir
path component ends with a path separator.
In order to benefit from the above improvements, along with increased
compatability with git_snpath() and git_pathdup(), we reimplement the
git_path() function using vsnpath().
