builtin/apply: make parse_ignorewhitespace_option() return -1 instead of die()ing

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_ignorewhitespace_option() should return -1 instead of calling die().
