openjdk11: include location changed

[Michael Osipov]

Folks,

I continued to test the new port against other projects and failed to 
compile jansi-native which is used in Maven. The subtile difference is:

> [mosipov at mika-ion /usr/ports/java/openjdk8]$ tree /usr/local/openjdk8/include/
> /usr/local/openjdk8/include/
> ├── classfile_constants.h
> ├── freebsd
> │   ├── jawt_md.h
> │   └── jni_md.h
> ├── jawt.h
> ├── jdwpTransport.h
> ├── jni.h
> ├── jvmti.h
> └── jvmticmlr.h

> [mosipov at mika-ion /usr/ports/java/openjdk8]$ tree /usr/local/openjdk11/include/
> /usr/local/openjdk11/include/
> ├── bsd
> │   ├── jawt_md.h
> │   └── jni_md.h
> ├── classfile_constants.h
> ├── jawt.h

> ├── jvmti.h
> └── jvmticmlr.h


freesbd vs bsd

in ports I see:

> ./work/openjdk-jdk11u-jdk-11.0.2-9-2/build/bsd-x86-normal-server-release/images/jdk/include/bsd/jni_md.h

Is that change on purpose?

Shall I open an issue with Jansi Native?
