orchestrator/geoip: add a benchmark for Iterate*Databases()

Now:

```
goos: linux
goarch: amd64
pkg: akvorado/orchestrator/geoip
cpu: AMD Ryzen 7 PRO 6850U with Radeon Graphics
BenchmarkIterDatabase/ASN-16                3376               457.0 ns/entry
BenchmarkIterDatabase/GeoIP-16              2410               754.5 ns/entry
```

Before 0a10764cc9:

```
goos: linux
goarch: amd64
pkg: akvorado/orchestrator/geoip
cpu: AMD Ryzen 7 PRO 6850U with Radeon Graphics
BenchmarkIterDatabase/ASN-16                2863               609.3 ns/entry
BenchmarkIterDatabase/GeoIP-16              3286               719.3 ns/entry
```

I was hoping for a bit more!
