Public bug reported:
Similar to bug 1764980, but this is failing on 4.4 KVM kernel.
And despite the KALLSYMS was not enabled, the module output is not the expected
zero.
FAIL: test_095_kernel_symbols_missing_proc_modules
(__main__.KernelSecurityTest)
kernel addresses in /proc/modules are zeroed out
