[fix] set encoding of README.rst explicit in setup.py (utf-8) (#2117)

## What does this PR do?

When installing searx on a centos-7 image [1] an encoding exception is raised from setup.py::

    command: /usr/local/searx/searx-pyenv/bin/python3 -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/usr/local/searx/searx-src/setup.py'"'"'; __file__='"'"'/usr/local/searx/searx-src/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'rn'"'"', '"'"'n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /tmp/pip-pip-egg-info-pidntzkq
         cwd: /usr/local/searx/searx-src/
    Complete output (7 lines):
    Traceback (most recent call last):
