[cairo] [PATCH 1/2] Fix warning: '*' in boolean context

[Uli Schlachter]

The full message is:

  warning: ‘*’ in boolean context, suggest ‘&&’ instead
      _cairo_malloc((unsigned) (a) * (unsigned) (size)))
                                   ^
  note: in definition of macro ‘_cairo_malloc’
      ((size) ? malloc((unsigned) (size)) : NULL)
        ^~~~
