gnupg: Split gpg and gpg-agent into a minimal gnupg-gpg package

Add minimal "gnupg-gpg" package containing just enough binaries to run
gpg and gpg-agent. Add dependency in normal "gnupg" package to preserve
old behavior.

Some applications like opkg don't need all functionality provided by
normal gnupg installations. This minimal package provides just enough
functionality to verify and manage keys in opkg, in order to minimize
disk overhead.
