[PATCH 1/1] tools/rv: ensure monitor name and desc are NUL-terminated

["unknownbbqrx" <dev@unknownbbqr.xyz>]

ikm_fill_monitor_definition() copies monitor name and description with
strncpy(), but does not guarantee NUL termination when source strings are
equal to or longer than the destination buffers.

Clamp copies to sizeof(dst) - 1 and explicitly append '\0' for both fields
to keep them safe for later string operations.
