Correct the name of a compiler option and fix the corresponding warnings

The option `warn_export_vars` was erroneously written as `warn_exported_vars`
in Makefiles of dialyzer and typer. As a result, `erlc` was silent about such
warnings (why on earth doesn't it complain on unrecognized options??) which
were corrected as part of this change.
