Use strlcpy instead of strcpy to avoid buffer overrun.

Coverity issue: 323514

Fixes: b767f8efc8 ("net/softnic: replace pointers with arrays")

The 4 patches in this series have the same title,
same explanation and same root cause.
Only the coverity ID is changing.
In this case, you can merge all patches together
and reference all coverity ids on the same line with commas.
