Invalid charset at EOF does not cause decoding error

* libguile/ports.c (peek_iconv_codepoint): If the input has no bytes,
there's little point in raising a decoding error here.  Therefore remove
the needless iconv acquisition, harmonising with suspendable-ports.
* test-suite/tests/ports.test ("port-encoding"): Update test to include
some input so that the exception gets raised.
