tegra: rtcpu: Fix build for Linux v6.12

Browse Source 
In Linux v6.12 the definition 'no_llseek' was finally removed. Since
Linux v6.0 it had been redefined as NULL. Add a test to conftest to
determine if 'no_llseek' is present and if not then it is no longer
necessary to populate this and we can leave as NULL.
