fbreader: 0.99.4 -> 0.99.6, switch to fetchFromGitHub, add more build options (#45840)

This, apparently, is not an official release (it's tagged, but the tarball is not
available on the official site), but this repo is the official repo mentioned on
the official site.

This fixes a bunch of very annoying bugs present in 0.99.4, e.g.

```
$ FBReader filename
```

does not crash anymore. Yay!
