Tom Zanussi 27242c62b1 tracing: Use strncpy instead of memcpy when copying comm for hist triggers ...

Because there may be random garbage beyond a string's null terminator,
code that might use the entire comm array e.g. histogram keys, can
give unexpected results if that garbage is copied in too, so avoid
that possibility by using strncpy instead of memcpy.
