Fix build on Linux

I was able to compile and run serpapi-search-cpp in Docker. I use Fedora
and package names are different. I found them all, but it's more
convenient to use existing container for compilation.

The simplest way to reproduce end-to-end build and run is to execute

```bash
env API_KEY=API_KEY docker run --rm -it -e API_KEY --workdir /tmp/serpapi -v $PWD:/tmp/serpapi conanio/gcc10 make install_linux reset all
```

This will use https://hub.docker.com/layers/conanio/gcc10 image instead
of creating our own image for compilation on Linux.
