[PATCH v3 2/2] gitlab-ci.yml: Add jobs to test CFI flags

[Daniele Buono <dbuono@linux.vnet.ibm.com>]

QEMU has had options to enable control-flow integrity features
for a few months now. Add two sets of build/check/acceptance
jobs to ensure the binary produced is working fine.

The three sets allow testing of x86_64 binaries for x86_64, s390x,
ppc64 and aarch64 targets
