usertools: warn about future removal of setup script

As agreed in the deprecation notice, the "generic" script
to setup the Linux environment will be removed in DPDK 20.11.
Some specific parts may be converted into dedicated scripts.

In the meantime, a warning will be printed to users of this script.
