Doesn't work on updated Ubuntu 22.04

[destmaster84]

Using Ubuntu 22.04 (updated via apt) the examples doesn't works anymore. When launching gnuradio flowgraph crashed with return code -11 . The problem seems to be related to ofdm_synchronization_impl block and the usage of VOLK, but I haven't investigated on depth. All the project should be updated and aligned with latest gr-dvbt and integrated in gnuradio package
