meta/lib: new module for handling GPG signing

Add a new Python module (oe.gpg_sign) for handling GPG signing
operations, i.e. currently package and package feed signing. The purpose
is to be able to more easily support various signing backends and to be
able to centralise signing functionality into one place (e.g.  package
signing and sstate signing). Currently, only local signing with gpg is
implemented.
