ximcp/imLckup: Handle negative return value from _Xlcwctomb

Fixed by negative value to memcpy by checking for the negative return
value of _Xlcwctomb and returning 0/XLookupNone in that case.

a negative value was passed to memcpy

Unfortunately the other return values for *status don't fit into the
error (which appears to indicate some internal error or running out of
memory). The other valid status codes are XBufferOverflow,
XLookupNone, XLookupChars, XLookupKeySym, and XLookupBoth. Each of
these has a specific meaning attached.
