Revert^2 "Add AddToDexClassloader JVMTI extension functions"

This reverts commit 799e536da9733ab638946f56e1ceb62d62cd3c81.

It seems that on some of our test devices the kernel does not have an
implementation for memfd_create. To work around this I added a basic
wrapper that will simulate memfd_create using temp files. This should
be sufficient for testing. All actual devices are expected to support
the memfd_create syscall natively.

Reason for revert: Implemented fallback for memfd_create
