cdio: Fix build with cdio >= 1.0

LIBCDIO_VERSION_NUM was defined as e.g. 94 for 0.94 but is now defined
as 1 for 1.0. We had various checks for < 83, which of course succeeded
now although we are >= 0.83.

Fix this by checking for < 76 (0.76) too, as that is the minimum version
we currently support and everything < 76 is going to be >= 1.0.
