[alpine:edge] gnupg --keyserver access broken - network issue?!

As-of-this-writing: With current **alpine:edge** this does **not** work:

```
docker run -it --rm alpine:edge sh

/ # apk add --no-cache gnupg
[... installation output]

/ # gpg --keyserver ha.pool.sks-keyservers.net --recv-keys 9554F04D7259F04124DE6B476D5A82AC7E37093B
gpg: directory '/root/.gnupg' created
gpg: new configuration file '/root/.gnupg/dirmngr.conf' created
gpg: new configuration file '/root/.gnupg/gpg.conf' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: keyserver receive failed: No such file or directory
```

But when I use the current **alpine:latest**, it does work:
```
docker run -it --rm alpine:latest sh

/ # apk add --no-cache gnupg
[... installation output]

/ # gpg --keyserver ha.pool.sks-keyservers.net --recv-keys 9554F04D7259F04124DE6B476D5A82AC7E37093B
gpg: directory '/root/.gnupg' created
gpg: new configuration file '/root/.gnupg/dirmngr.conf' created
gpg: new configuration file '/root/.gnupg/gpg.conf' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: /root/.gnupg/trustdb.gpg: trustdb created
gpg: key 6D5A82AC7E37093B: public key "Christopher Dickinson " imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1
/ #
```

Seems like network is somehow broken? But apk went just fine...

Thanks for taking care! Alpine rocks! ;-)
