Consider removing ncurses dependency

[nurmukhametov]

It is not quite clear whether we actually use that via LLVM. We may build LLVM with LLVM_ENABLE_TERMINFO=OFF. After that, we don't need to provide ncurses, e.g., here:

ispc/docker/centos/7/cpu_ispc_build/Dockerfile

Line 74 in 2eb90ed

RUN git checkout 87c2c84 && CFLAGS="-fPIC" CXXFLAGS="-fPIC" ./configure --with-termlib && make -j"$(nproc)" && make install -j"$(nproc)"

, as well as track it as third-party open-source dependency and etc..
