kola/kernel-replace: Replace kernel based on OS_ID

In one of the older issues, kola switch-kernel test was failing. In the discussion @jlebon suggested to remove named test and make it external, so that it can be utilized by FCOS, and also SCOS/RHCOS.
Additionally, the kernel version for FCOS was updated in this PR to the latest stable version `6.9.8-200.fc40`.

See: coreos/coreos-assembler#1245
