Fix the petalsearch engine

[mod] disbale engine tineye by default

Spelling: Tor, SearXNG

Currently translated at 76.3% (207 of 271 strings)

Translation: ecloud/Spot
Translate-URL: https://i18n.e.foundation/projects/ecloud/spot/nl/

Tineye becomes active as soon as a https:// signature is found in the search
term, but most of the time a reverse image search is not requested when a URL is
specified, often the URL is just from a C&P.

The frequent requests to tineye lead in the end to the SearXNG instance being
blocked by tineye and the user seeing unexpected error messages.

BTW: many maintainers have disabled this engine in their local SearXNG settings.

[fix] make nvm.env exit with error when VERBOSE is unset

    $ make nvm.install
    INFO:  install (update) NVM at /800GBPCIex4/share/SearXNG/.nvm
    INFO:  already cloned at: /800GBPCIex4/share/SearXNG/.nvm
      || Fetching origin
    INFO:  checkout v0.39.1
      || HEAD is now at 9600617 v0.39.1
    make: *** [Makefile:96: nvm.install] Error 1

Without this fix we need to set VERBOSE environment to avoid the 'Error 1':

    $ VERBOSE=0 make nvm.install

BTW: fix an issue if there are any leftovers in ${NVM_DIR} from previos
installations

[fix] remove engine neeva from settings.yml

Engine is broken and can't by used any longer as a simple XPath engine.
@allendema tested a engines/neeva.py version using json from the dom, but
without luck: There was some kind of captcha for pagination.

Before this patch SearXNG returns 'time_range': 'None'::

    <form method="GET" action="/searx/search">
      ...
      <input type="hidden" name="time_range" value="None">
      ...
    </form>
