[PATCH dpdk] buildtools/cmdline: fix meson error when used as a subproject

[Robin Jarry]

Fix the following error when using dpdk as a subproject:

 subprojects/dpdk/buildtools/subproject/meson.build:28:56:
 ERROR: Unknown function "file".

This was obviously never tested in its submitted form.

Cc: stable at dpdk.org
Fixes: 7d8c608faa7f ("buildtools/cmdline: allow using script in subproject")
