[xaprepare] update Debian dependencies for current unstable (trixie) (#8169)

Current Debian/unstable (otherwise known as sid), codename trixie, made libncurses5-dev a
transitional package and the package replacing it is libncurses-dev

Update `xaprepare` to install the new package on systems running Debian `trixie` (13) or
newer.
