requirements: Add all mandatory requirements

The requirements are quite outdated, this commit adds all of them to
both, requirements.txt and setup.py in order to just install avocado-vt
and get all required dependencies installed automatically.

The `avocado-framework` dependency is not included in requirements.txt
as 36lts used a different name. This is treated in setup.py but there is
no way to workaround it in requirements so only comment is there.
