Use 1.4 version of net_config_get_interfaces

Apparently Android API 3 does not know the getMTU() function, which was
added in Java 1.6, and in Android API Level 9 (Gingerbread). Therefore,
fall back to the 1.4 version that does not need this API.
Add animal-sniffer-plugin for Android API

Include the animal-scents for Android API in this commit, so that users
who do not have Android SDK can still check meterpreter API compatibility
with Android API. Some classes, like screenshot have been excluded since
they need AWT (but they are excluded in Android Meterpreter anyway).

To regenerate the scents file, run

mvn -Dandroid.sdk.path=... -P regenerate package
