Revert "Remove invalid meson keyword argument "console""

This reverts commit 5af0bf1405.

The "console" keyword is introduced in the future meson version 0.48,
I've viewed the warning compiling and I thought that was an old keyword
so I removed it, but Jordan told me that's correct so I'm reverting.
