feat(wpcarro/configs): Define {import,export}-gpg in Nix r/3679

Note: Calling `export-gpg` (relying on the symlink to `__dispatch.sh`) hangs
because it's prompting the user for the password to decrypt the secrets, but for
some reason no prompt displays. When I call...

```shell
$ nix-build /depot -A users.wpcarro.configs.export-gpg
$ ./result
```

...it WAIs. I need to debug this, but I'm committing the work for now because
it's making my `magit-status` noisy.

TODO(wpcarro): Merge and reconcile configs, dotfiles.
