plugins.d/mandos-client.c (get_flags): Use strncpy(), not strcpy().

* plugins.d/mandos-client.c (get_flags): Use strncpy() instead of
  strcpy().  Note that as the code works currently, this is never a
  problem in practice, since only interface names which were valid
  existing interface names (and therefore had names with lengths below
  IF_NAMESIZE) is ever passed to the get_flags() function.  But it
  doesn't hurt to check, anyway.
