Since commit 947dbc92a2 the Bootlin
stable toolchain uses headers 5.4, which can lead to build outputs
incompatible with older kernels. Update to the latest 5.4 kernel to
avoid this. The kernel config is updated according to the requirements
of current Docker, runc, and crun.
Additionally switch the CPU of the test VM to Haswell, to avoid
dockerd failing to start with a "This program can only be run on AMD64
processors with v3 microarchitecture support" error.
