refactor(filter_audio): completely remove filter_audio dependency

Browse Source 
The filter_audio API is not working for qTox/Tox and thus disabled by default via compiler switch. In current qTox UI, it is not configurable, even when this switch is enabled. According to issue #3194 the library is no longer maintained as well. I don't see any reason to keep it in qTox.

### filter_audio
This step is best done before compiling toxcore.
Now you can either follow the instructions at
https://github.com/irungentoo/toxcore/blob/master/INSTALL.md#unix or use the
[`bootstrap.sh`](/bootstrap.sh) script. The script will automatically download
and install `toxcore` and `libfilteraudio`:
```bash
## in qTox directory
./bootstrap.sh # use -h or --help for more information
```
If you've used script, you can skip directly to [compiling qTox](#compile-qtox).
If you want to compile and install it manually:
```bash
git clone https://github.com/irungentoo/filter_audio
cd filter_audio
make -j$(nproc)
sudo make install
```
### sqlcipher
If you are not using Fedora, skip this section, and go directly to compiling

```
Next, install [filter_audio](https://github.com/irungentoo/filter_audio) (you
may delete the directory it creates afterwards):
```bash
git clone https://github.com/irungentoo/filter_audio.git
cd filter_audio
sudo make install
cd ../

Next, install
