[Fuchsia] Add ASAN_OPTIONS in asan build

fuchsia-fyi-x64-asan build is broken due to detect_odr_violation in
rust.[1] and search for "odr-violation" in [2].

It's a known issue [3] and also impacts other platforms [4].

A previous attempt to disable the
sanitize-address-globals-dead-stripping
(in https://crrev.com/c/4690811) fixed media_unittests but broke
base_unittests. So I ended up deciding to follow the suggestion from
the sanitizer itself to use the environment variable.

Since there isn't a asan try, it takes 6+ hours to run, I have to
manually test the change locally. With this change, both media_unittests
and base_unittests are passing when is_asan = true in gn args.
