ci: 'temporary' disable sanitizers for 32bit builds

Currently running 32bit tests alongside sanitizers, segfaults due to our
syscall wrapper. Just disable the sanitizers, which means we get at
least some 32bit test coverage.

On a couple of attempts, I wasn't able to get a proper/robust solution,
as outlined in init_module.c - we need vsyscall() which does not exist.

Considering some distributions are dropping 32bit/i686 support, it may
be that we'll nuke these builds from CI sooner than later.
