netsniff-ng: Explicitely NULL-terminate readlink() result buffer

Commit 6c5d0caf3b7c ("netsniff-ng: Fix process name when sniffing nlmon
device") fixed the problem of not NULL-terminating the readlink() result
buffer by initializing the entire buffer with '\0'.

Switch to the more common and better readable idiom of explicitely
writing a NULL byte after the readlink result string to make this more
obvious. Also change the buffer size to PATH_MAX.
