[test/invalid-matrix] Disable floating point exception.
test/invalid-matrix purposely feeds invalid numbers into cairo, in
order to check its detection of garbage values. In doing so, cairo
raises an Invalid exception, but as this is a direct result of an abuse
of the API we can treat it as expected behaviour and ignore the
exception.
