[mod] multithreading only in searx.search.* packages

it prepares the new architecture change,
everything about multithreading in moved in the searx.search.* packages

previously the call to the "init" function of the engines was done in searx.engines:
* the network was not set (request not sent using the defined proxy)
* it requires to monkey patch the code to avoid HTTP requests during the tests
