logos-delivery#3949 collapses libwaku into liblogosdelivery so a single
C library exports both the waku_* and logosdelivery_* ABIs. Point the
libwaku bridge at liblogosdelivery (header + -llogosdelivery) and route
its event registration through logosdelivery_set_event_callback, since
the waku-specific set_event_callback no longer exists.
With one shared library the two bridges no longer carry overlapping
symbols, so drop the "must not link together" caveats from the package
docs.

Add internal/ffi/liblogosdelivery, the cgo bridge over liblogosdelivery
(Messaging API), mirroring the libwaku subpackage from #114: synchronous
request/response plumbing, a shared async event callback, and a handle->handler
registry, exposing Go-typed primitives (New/Start/Stop/Destroy,
Subscribe/Unsubscribe/Send, SetEventHandler, Handle, RetOK, EventHandler).
It self-links liblogosdelivery via a #cgo directive. For symmetry — and so the
two bridges never need a shared global -l flag — add the same #cgo LDFLAGS:
-lwaku to the libwaku subpackage. Each subpackage now links exactly its own
library; no binary links both (until logos-delivery#3851).
Extend the PR gate to build liblogosdelivery, set CGO_CFLAGS for both headers
with no -l (each package self-links), run the messaging unit tests, and compile
the kernel tests.
Part of #106.
