Arthur Gautier 256c518a8a dpdk: fixup shared compilation
Dpdk build will default to static linking of its libraries if
`default_library` option is not specified. When shared is expected, we
should explicitely set the `default_library` option to `shared`.

This saves 586MB on the derivation output size:
