copy some javacpp-preset sample project build.gradle fragment here in…

This does not really help resolving dependencies to incorrect platform-
specific libs e.g. it tries to resolve rtmidi-javacpp-macos-x86_64 even

Looks like bytedeco/gradle-javacpp#24 is a
relevant issue, but it seems unresolved forever.
