gpg_sign: add local ipk package signing functionality

Browse Source 
Implement ipk signing inside the sign_ipk bbclass using the gpg_sign
module and configure signing similar to how rpm does it. sign_ipk uses
gpg_sign's detach_sign because its functionality is identical to package
feed signing.

IPK signing process is a bit different from rpm:
    - Signatures are stored outside ipk files; opkg connects to a feed
server and downloads them to verify a package.
    - Signatures are of two types (both supported by opkg): binary or
ascii armoured. By default we sign using ascii armoured.
    - Public keys are stored on targets to verify ipks using the
opkg-keyrings recipe.
