Subject: [PATCH] test: pre-load ASan's DSO for iscsi-init.service

The iscsi-init.service calls `sh` which might, in certain circumstances,
pull in instrumented systemd NSS modules causing `sh` to fail. Let's mitigate
this by pulling in an env file crafted by `create_asan_wrapper()` that
(among others) pre-loads ASan's DSO.
