This change updates the build script to include objtool in the header
package, which is necessary when building some out-of-tree modules (such as
the NVIDIA driver)
The upstream Ubuntu kernel enables UBSAN on 5.14+ and 5.13.14+ builds, leading
to boot issues on servers depending on the hardware or module configuration.
With hundreds of different kernel modules and thousands different
configuration, this change in its current stage is high risk and questionable
in general.
These issues are impossible to predict and hard to troubleshoot.
Therefore, I believe it is worth disabling for now.
Resolves#164 and #200
