Bug description:
  == Justification ==
  In Xenial KVM kernel, the CONFIG_DEBUG_KERNEL is enabled, security team would like to see CONFIG_DEBUG_RODATA to be enabled as well.

  == Test ==
  Before enabling the config the test_072_config_debug_rodata test from qa-regression-testing will fail. After that, the test will pass.
  A test kernel with CONFIG_DEBUG_RODATA enabled in Xenial KVM could be found here:
  http://people.canonical.com/~phlin/kernel/lp-1760643/

  == Fix ==
  Enable the CONFIG_DEBUG_RODATA.
  Some other configs were enabled just for skipping the interaction during the compilation.

  == Regression Potential ==
  Minimal.
  No code changes, just one config enabled without disabling any other configs.

  The test failed with:
    FAIL: test_072_config_debug_rodata (__main__.KernelSecurityTest)
    CONFIG_DEBUG_RODATA/CONFIG_STRICT_KERNEL_RWX enabled
    ----------------------------------------------------------------------
    Traceback (most recent call last):
      File "./test-kernel-security.py", line 642, in test_072_config_debug_rodata
        self.assertEqual(self._test_config(option), expected)
    AssertionError: False != True

  Steps to reproduce:
    Deploy the node with Xenial 4.4 kernel, install linux-kvm
    sudo apt-get install python-minimal
    git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests -b master-next
    git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
    rm -fr autotest/client/tests
    ln -sf ~/autotest-client-tests autotest/client/tests
    AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_qrt_kernel_security/control
