stdenv, cmake: drop --oldincludedir

Without the change the build of upcoming `sqlite-3.49.0` will fail as:

    > Error: Unknown option --oldincludedir
    > Try: 'configure --help' for options

Looking at https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
it feels like it's something that predates gcc and
it should be an alias to `--includedir=`.

Let's just drop the setting of `--oldincludedir=`
(and `cmake` equivalent).
