[ANDROID] android compatible methods in azure core flagged by animal sniffer

[jr1000000]

Animal Sniffer identifies java.lang.invoke.MethodHandle.invoke and java.lang.invoke.MethodHandles.Lookup as not compatible with any android or java signatures.

animal-sniffer output on azure-core:

This occurs anytime animal-sniffer:check is run against azure-core.

java.lang.invoke.MethodHandle.invoke is supported under android api level 26 so these signature mismatches should not be flagged.
It is likely a result of issue mojohaus/animal-sniffer#67
