Objenesis can't be compiled on Android SDK < 26

[henri-tremblay]

See mockito/mockito#2007.

The current possible solution can be to remove "exotic" instantiator from objenesis-core. We should have a test to make sure it works.

@henri-tremblay The main issue for supporting android SDK < 26 is any mention of MethodHandle in the bytecode.

The Java 11 support added this and broke Android. -> 5f9d20b

I think it will be hard to have a single jar that works on android API < 26 and JDK 11+.

Providing multiple different artifacts is one possible solultion. Perhaps with a -jdk7 and -jdk11 maven classifier?

I'm a bit overwhelm these day. I do hope I will have the time to revisit soon. If anyone has the time, feel free to look.
