python3Packages.dlib: support sse4 instructions
My understanding of the line that is removed is, that the logic is
wrong. According to the setup.py file[0] it says that:

> To exclude certain options in the cmake config use --no:
>     for example:
>     --no USE_AVX_INSTRUCTIONS: will set -DUSE_AVX_INSTRUCTIONS=no

This means, that a true value of `avxSupport` will deactivate it in the
setup, which is not what we want.
