R36 and "bring our own kernel"-feature related conftests fixes.

[TanelDettenborn]

Jetson R36 introduces "bring your own kernel"-feature. Nvidia-oot requires a couple of fixes to work against upstream kernel. Note: Tested with kernel 6.6.118. Later kernel might require more adjusting of nvidia-oot.

Description of changes

• Nix adds "format-security" GCC flag and therefore one of the NVIDIA's "conftest"-test error erroneously.
• Display driver is missing "of_property_for_each_u32_removed_internal_args"-conftest

Testing

nix build .#flash-orin-nx-debug && nix build .#iso_minimal evaluates and compile (and boots on NX device). Targets has been tested with default BSP 5.15.x kernel and upstream 6.6.118 kernel.

We don't have the bandwidth to "bring your own kernel". I'm happy to help take work to support BYOK, but we might inadvertently break (or be forced to break) BYOK. If we know that the patches don't apply and can't trivially fix them up, we can tag you and give some time to clean up the patches.

I assume there's more to add support for the 6.6 kernel than just these 2 out-of-tree module patches?

Lists the patches, and which kernel they landed in. depending on your baseline kernel, so if you have a 6.6 you need to apply 6.7 and next.

The full patch for the 6.6 kernel is there, rebased yesterday, including the changes in this PR. We have had it in use and testing for quite some time.

If you'd like to add support for 6.6 kernel in jetpack-nixos, I'd like to bring in all the changes rather than just a subset of them.
