input/curl: don't abort if a packet has only metadata
When a received chunk of data has only icy-metadata, there was no usable data left for input_curl_read() to return, and thus it returned 0 bytes. "0" however is a special value for "end of file" or "error". This patch makes input_curl_read() read more data from the socket, until the read request can be fulfilled (or until there's really EOF).
