ci : set GGML_NATIVE=OFF for bindings-java

This commit attempts to address an issue with the bindings-java job
which is currently failing.

I've not been able to reproduce this locally my windows machine and I
suspect that what might be happning is that windows job compiles on a
runner where it has different CPU features, for example AVX512 and when
this dll is used on a different runner that does not have that feature
it will crash.
