test(hw): strip debug scaffolding from ADRV9009+ZC706 test

Removes the clk_summary / jesd204 debugfs / clk_set_rate dmesg
dumps that were only useful while chasing the JESD link-up
blocker (fixed in 9a7e2e2).  Drops the now-unused shell_out
import.  Test still passes end-to-end on nemo (verified).
