www/py-searx: Update to 0.14.0

Port changes:

• Changed DISTVERSION
• Switched to CHEESESHOP
• Updated COMMENT
• Updated RUN_DEPENDS
• Replaced USE_PYTHON=concurrent with USE_PYTHON=noflavors
• Patched requirements.txt to require on >= basis
• Removed tests inslall (conflicts with other such packages)
• Move settings under /etc
• In searx.in, used %%PYTHON_CMD%% instead of the hardcoded command
• Fixed searx.in to actually start and stop the service (it was broken)
• Added pkg-message explaining how to use it

Testing:

• runs fine

This package allows you to get rid of tracking by the search providers
(google, bing, etc). You can either use the local service on
http://localhost:8888, or one of the external instances, ex. https://searx.me/
