seq: produce consistent error messages upon write error

* src/seq.c (io_error): Use the same error message as would
be generated at exit time when closing the stdout stream.
The inconsistency was added with commit v8.25-26-gc92585b.
This was noticed due to an inconsistency in the expected
error message generated by seq on musl libc.
