Fix install path for sanitized native tests. (Soong)

This CL fixes a bug with how Soong builds the install path for native
tests. Tests are installed in /data/nativetest* by default, but the
logic was wrongly redirecting sanitized versions to
/data/asan/system/nativetest*. With this fix, they are correctly
redirected to /data/asan/data/nativetest* instead.

Bug: 37942061
Test: lunch marlin_asan-userdebug && \
        SANITIZE_TARGET="address" m -j70  \
        # nativetests are generated in /data/asan/data/nativetest*
