Drop support for Django < 1.11 and remove workarounds

Per Django's recommendation, as django-silk supports 2.0, it should drop
support for Django < 1.11 to ease maintenance and compatibility across
Django versions. So long as no deprecation warnings are produced,
django-silk should remain forward compatible with the next Django
version.

For more details, see the Django docs:

https://docs.djangoproject.com/en/2.0/releases/2.0/#third-party-library-support-for-older-version-of-django

> Third-party library support for older version of Django
>
> Following the release of Django 2.0, we suggest that third-party app authors
> drop support for all versions of Django prior to 1.11. At that time, you
> should be able to run your package’s tests using python -Wd so that
> deprecation warnings do appear. After making the deprecation warning fixes,
> your app should be compatible with Django 2.0.

Those wishing to continue using an older Django can pin the version
django-silk.

Should significantly reduce testing resources as the test matrix is much
smaller.
