Update the HelloActivity.apk bundled with ApiDemos, used to demonstrate the package installer API.

The current APK was built to target the ICS SDK, and cannot be installed on newer versions:
"Failure [INSTALL_FAILED_OLDER_SDK: Failed parse during installPackageLI: /data/app/vmdl1087711068.tmp/base.apk (at Binary XML file line #0): Requires development platform IceCreamSandwich (current platform is any of [P])]"

The APK I'm checking in was built from development/samples/HelloActivity, with this added to the manifest:
    <uses-sdk android:minSdkVersion="23" android:targetSdkVersion="23" />
This is the same as the ApiDemos app's minSdk and targetSdk.

Test: Manually rebuilt ApiDemos, and installed the package using the InstallApk activity.
