android_app APEX_GLOBAL_MIN_SDK_VERSION_OVERRIDE

Currently the product variable that is controlled by
APEX_GLOBAL_MIN_SDK_VERSION_OVERRIDE only overrides apexes, but it
doesn't apply to android_apps. This commit allows android_apps which set
updatable: true in their Android.bp to have their min_sdk_version be
overriden by this product variable.
