ipa-backup and ipa-restore now use GnuPG 2 for asymmetric encryption, too.
The gpg2 command behaves a bit different and requires a gpg2 compatible
config directory. Therefore the --keyring option has been deprecated.
The backup and restore tools now use root's GPG keyring by default.
Custom configuration and keyring can be used by setting GNUPGHOME
environment variables.
