Bug 521515: Align directory name of native source code

The native directory can contain both libraries and utilities. In
Gerrit https://git.eclipse.org/r/c/cdt/org.eclipse.cdt/+/165270,
there is a utility, so the directory name "jni", or even "library" does
not work. In order to support both utilities and libraries, the
suggested name of the directory is "native_src" and thus, this commit
syncs that change in o.e.c.native.serial.
