Deps Builder: Disable TermInfo and ncurses for DPC++

They are not strictly needed for compilation and disabling them makes
the compiler more portable without any special trickery.

This change aimed to solve problem which currently happens on the API
documentation build which does not have terminfo installed, but needs
to compile Cycles.

Note that the DPC++ is to be re-compiled.
