test_072_config_debug_rodata in kernel security test failed with 4.4

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
