[dpdk-dev] [PATCH] app/testpmd: fix copying the name of the dynflag

[Ori Kam]

When working with testpmd and setting the dynflag name, we copy the
name given by the cmd to the dynflag name.

The issue is that the size of the dynflag name is smaller then the
string used by testpmd.

This commit solves this issue by usign strncpy.

Coverity issue: 353610
