fix(aarch64): disable CONFIG_ARM64_ERRATUM_3194386 option

Disable CONFIG_ARM64_ERRATUM_3194386 option in the guest kernels for aarch64. It is enabled by default and makes `ssbs` feature to not be user space visible. This breaks out integration tests. This option is only indented for `Cortex-X4` and `Neoverse-V3` cpus which we are not using, so disabling it is safe. Signed-off-by: Egor Lazarchuk <[email protected]>
