test_190_config_kernel_fortify in kernel security test failed with 4.15 KVM kernel

[Po-Hsu Lin]

== Justification ==
In the Bionic KVM kernel, the CONFIG_FORTIFY_SOURCE and
CONFIG_SECURITY_PERF_EVENTS_RESTRICT were not set, they need to be enabled to
meet the security team's requirement.

== Test ==
Before enabling the config, test case test_190_config_kernel_fortify and
test_250_config_security_perf_events_restrict will fail in the kernel
security testsuite for the kernel SRU regression test.

It will pass with these two patches applied, tested on a KVM node.

== Fix ==
Set CONFIG_SECURITY_PERF_EVENTS_RESTRICT to "y".
Set CONFIG_FORTIFY_SOURCE to "y".

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