[dpdk-stable] [PATCH] install: fix flattening of examples directory

[Bruce Richardson <bruce.richardson@intel.com>]

By installing the examples one-by-one in a loop in the examples
meson.build file we effectively flatted out the structure of the examples
folder and omitted some common and shared subfolders that were never
directly built.  Instead, we can remove the loop and just have the whole
"examples" folder installed as-is in a single statement, preserving its
directory structure, and thereby fixing the build of a number of the
examples.

Fixes: 2daf565f91b5 ("examples: install as part of ninja install")
