ti-ipc: explicitly depend on virtual/kernel:do_shared_workdir

ipc code looks for kernel's generated version.h file:
  #include linux_version_include(KERNEL_BUILD_DIR)

which now ends up in the following shared workdir:
  work-shared/<mach>/kernel-build-artifacts/include/generated/uapi/linux/version.h

It appears if kernel is provided by sstate, shared workdir is not
getting populated, so depend on the task explicitly.
