dev-libs/cdk: build with --enable-const

I don't understand why, in the year 2023, this is optional or at the very least
not default-on, but whatever.

It turns out that Fedora and openSUSE at least, probably many others, are building
cdk with --enable-const which is why this only showed up on Gentoo. We do the same
--enable-const dance for ncurses so I suppose I should've known.

Enable it for parity given it should be fine to go in this direction anyway.
