iso7816: if index is beyond file, return EOF

commands for data unit handling may return 6B00 if the specified index
is too large (ISO 7816-4). Maybe SC_ERROR_OFFSET_TOO_LARGE would be more
appropriate, but this is (1) currently not used only for internal errors
and (2) this error code is not currently handled by sc_read_binary.
Hence, we stick to SC_ERROR_FILE_END_REACHED.
