[dpdk-dev] [PATCH v2 4/7] build: move pkg-config creation to separate file

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

Ahead of changes to rework the file, move the pkg-config file generation to
a new directory under buildtools. This allows the meson code to be
separated out from the main meson.build for simplicity, and also allows any
additional scripts for working with the pkg-config files to be placed there
too.
