Fix: runtime apex is not instrumented with sanitizer

Fixing the problem that IsSanitizerEnabled always returns false due to
the different sanitizer names from config.SanitizerDevice() and
sanitizerType.String().

Test: SANITIZE_TARGET=hwaddress m com.android.runtime.release

Test: inspect out/soong/build.ninja
- Variant of com.android.runtime.release is "android_common_hwasan_com.android.runtime.release"
- Dependencies of com.android.runtime.release are hwasan variants: e.g.,
  out/soong/.intermediates/bionic/libc/libc/android_arm64_armv8-2a_kryo385_core_shared_hwasan_com.android.runtime.release/libc.so

Test: ls out/soong/.intermediates/art/build/apex/com.android.runtime.release/android_common_hwasan_com.android.runtime.release/image.apex/lib64/*.so  | xargs readelf -d | grep libclang_rt.hwasan | wc -l
