worktree: use xsize_t to access file size
To read the "gitdir" file into memory, we stat the file and allocate a buffer. But we store the size in an "int", which may be truncated. We should use a size_t and xsize_t(), which will detect truncation. An overflow is unlikely for a "gitdir" file, but it's a good practice to model.
