builtin/apply: make add_index_file() return -1 on error
To libify `git apply` functionality we have to signal errors to the caller instead of die()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", add_index_file() should return -1 instead of calling die().
