I understand your point that packaging could handle filtering out unwanted files.
However, adding a build option to disable DPDK examples source code installation provides
more control and flexibility for users who may have specific requirements or constraints.

While packaging can filter out files, this option allows users to avoid
downloading and compiling the examples altogether, which can be beneficial for:

- Users with limited disk space or network bandwidth
- Users who only need the core DPDK libraries and binaries and don't want the examples source code.

By default, the option is set to true, so the behavior remains unchanged.
This option is only for those who need more control over their build process.
I believe this optional flag adds flexibility without imposing unnecessary files on users and is a minor
and useful extension to the build system.
