cointainers: add kernel build dependencies and tuxmake to CI container

Enhance the Fastpath CI container to support kernel regression
bisection by installing required build tools and TuxMake (v1.29.3).
TuxMake is installed via pip to ensure consistent kernel builds using
the same toolchain across environments.

Embedding tuxmake in the container eliminates variability in toolchains
and ensures that kernel builds during bisection are uniform.
