Gradle, native: Produce binaries from klibs and bump K/N version

Earlier all native binaries were produced directly from sources of
corresponding compilations. This patch changes this behavior. Now
a klibrary produced by a compilation is used to build a final
binary instead of sources. This allows us to avoid parsing the same
sources several times and reduces build time.

This patch also updates K/N version to 1.3.60-dev-11975, to get the
corresponding support from the compiler side.
