6a936580d1 ci: remove RUN_SECURITY_TESTS (fanquake)
Pull request description:
We no-longer run any security/symbol checks in the CI, and doubt we will in future (if we do, it'll be via Guix, where this var would be redundant in any case). The CI environment doesn't (exactly) match the release build environment (and is semi-regularly changing), and the binaries produced in the CI don't match how we build release binaries, so there is no point trying to run these checks, especially as we add more involved tests, i.e #26953.
