sage: fix TeX Live input

The Sage derivation had texLive, the old TeX Live packaging which
is now marked as broken, as a build input. This replaces it by the
current TeX Live packaging.

However, the build remains broken. One of the problems can be
solved by patching the hashbangs at the beginning of build scripts,
but the build still gets stuck while building ncurses.
