Use "nomodule" instead of manual check 

Very few browsers are left in the wild that supports modules but not
"nomodule", so let's simplify our handling a bit.

Safari 10 supports modules but not 'nomodule', this means that this
particular version of Safari will be broken. Due to this we have to
bump up the required Safari version to 11.
