`updatekeys` appears to ignore the config file switch

[KayEss]

Probably somewhere around this line needs to also check if the --config file switch was used and change accordingly https://github.com/mozilla/sops/blob/master/cmd/sops/main.go#L421

Our workaround is to rotate the key: sops -i -r <file> which does honour the --config switch.

The workaround doesn't work :-( It just rotates the secret for the existing keys. Probably decrypting and re-encrypting (editing the file) will do it.

Fixed with #672
