Suppress Java native code warnings

This MR resolves 1131128.

Changes:

• add command line options to suppress native code warnings.

Note: I have added -XX:+IgnoreUnrecognizedVMOptions to keep things backwards compatible.

Testing:

• running puppetserver cli does not produce the native code warnings:

puppetserver ruby -e " print \"ok\n\" "
