builtin/apply: make parse_traditional_patch() 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", parse_traditional_patch() should return -1 instead of calling die().
