package/opkg: move related code together

In commit d31db33 (opkg: Add gnupg signature checking support.),
the macro definition for the hook, and the hook assignment, got
separated by the then-newly introduced GPG handling.

Move the macro definition closer to the hook assignment. Since this is
a post-install hook, it is but logical that it comes further down in
the .mk file.
