[PATCH 7/9] sandbox: rename KASan to ASan

sandbox really has ASan support, that is address sanitizer with the help
of the userspace library libasan. In contrast KASan is used on real
hardware where we have to implement our own support code. Rename sandbox
KASan to ASan to not clash with upcoming KASan support.
