macvlan: Replace strncpy() by strscpy()
The strncpy() function is being deprecated. Replace it by the safer
strscpy() and fix the following Coverity warning:
"Calling strncpy with a maximum size argument of 16 bytes on destination
array ifrr.ifr_ifrn.ifrn_name of size 16 bytes might leave the destination
string unterminated."
Notice that, unlike strncpy(), strscpy() always null-terminates the
destination string.
Addresses-Coverity-ID: 1445537 ("Buffer not null terminated")
