test_095_kernel_symbols_missing in ubuntu_qrt_kernel_security failed on Bionic

This issue could be found on AMD64, ppc64le, ARM64, s390x (not sure about i386, which was not tested because of the deployment issue in the last cycle)

Steps:
 1. Deploy an AMD64 system with Bionic
 2. sudo apt-get install git python-minimal -y
 3. git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests -b master-next
 4. git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
 5. rm -fr autotest/client/tests
 6. ln -sf ~/autotest-client-tests autotest/client/tests
 7. AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_qrt_kernel_security/control
