preload asan if we are compiling with ECM_ENABLE_SANITIZERS

This is not tested as I could not reproduce in local the same build system as the CI.

I've read the thread ecmenablesanitizers and the previous fix (which has been reverted a month later): 524bbb6d. I've used the same path as this commit.

The other solution I read is exporting ASAN_OPTIONS=verify_asan_link_order=0 but I don't know the side effects too... (but it won't need to harcode the path to the asan library)
