test_260_config_arm_pan from kernel_security_test failed on Artful ARM64 system

[Po-Hsu Lin]

It looks like this test should be skipped on Artful (kernel < 4.15)
But the result returned FAIL instead.

  Ensure PAN for arm processors is set ... (skipped: CONFIG_ARM64_SW_TTBR0_PAN added/enabled in 4.15 and newer) FAIL

  ======================================================================
  FAIL: test_260_config_arm_pan (__main__.KernelSecurityTest)

Also, this CONFIG is available in 4.13 kernel:
$ grep ARM64_SW_TTBR0_PAN /boot/config-4.13.0-39-generic
CONFIG_ARM64_SW_TTBR0_PAN=y

Thanks, the test was FAILing on artful/arm64 precisely because it was expecting not to find CONFIG_ARM64_SW_TTBR0_PAN set in the 4.13 kernel config, and it was. I have fixed up the qrt script in
https://git.launchpad.net/qa-regression-testing/commit/?id=631ed1d195a7a9499caf3e4b5807ba2e423810e0 .

Thanks!
