sagemathgh-36219: configure.ac: disable webencodings,tinycss2 with --…

…disable-notebook

The `--disable-notebook` flag disables the bleach and nbconvert
packages, and the webencodings and tinycss2 packages are (solely)
dependencies of those. We can therefore disable webencodings and
tinycss2 whenever `--disable-notebook` is given.
