The vdso* files are built into the kernel for loading into userspace binaries to accelerate various kernel-related operations. These files do not need to be packaged & installed for the system to operate, and indeed they aren't part of the linux-image* deb's in Ubuntu. However, tools such as systemtap (and possibly perf and oprofile; https://bugs.launchpad.net/ubuntu/+source/oprofile/+bug/295975) need them, in order to unwind user-space stacks.

In Fedora, these vdso.so's are installed with:

   [...]
    %{make} -s ARCH=$Arch INSTALL_MOD_PATH=$RPM_BUILD_ROOT vdso_install KERNELRELEASE=$KernelVer
   [...]

so they show up under /usr/lib/modules/`uname -r`/vdso/.

Please make the change to have the linux-image deb preserve & ship these .so's in the same location.
