docker: BuildKit cache + CGO LTO optimization

Browse source 
Add persistent cache mounts for the Go module cache, Go build cache,
and apt so only changed packages are re-downloaded or recompiled on
subsequent builds.

CGO LTO is injected via `make LIBFIDO2_LDFLAGS=...` rather than ENV
because the Makefile sets CGO_LDFLAGS inline in go-build-finalize,
clobbering any inherited environment variable. Binary stripping is done
with strip --strip-all post-build since the Makefile owns the -ldflags
chain and cannot be extended without losing the -X version constants.
