Currently libnativeloader appends vendor lib path if apk is from vendor partition. Similar to this we should add product lib path if apk if from product partition. Bug: 124705551 Test: m -j && tested from crosshatch with product apps (such as Wallpaper) Change-Id: I8c3473f1f70b1c22dcaed7eb2d5f9c3deee9e1a5 Merged-In: I8690167ca8098015c8ae4bbb4f028404c5e94dc0
