It's better to

1. Use strlcpy() instead of strncpy() as otherwise we might end up
   with a not NULL-terminated string, which opens a portal to hell.
   There are a few places reported by Coverity for this, such as:
    - in criu_connect(), Coverity CID 51591;
    - in proc_pid_parse(), Coverity CID 51590;
    - in move_veth_to_bridge(), Coverity CID 51593;
    - etc.

2. Use strlcpy() instead of strcpy() to avoid buffer overruns.
   Some of these are also reported by Coverity, for example
   the one in dump_filemap(), Coverity CID 51630.
