SUNRPC: Fix buffer overflow checking in gss_encode_v0_msg/gss_encode_v1_msg
In gss_encode_v1_msg, it is pointless to BUG() after the overflow has happened. Replace the existing sprintf()-based code with scnprintf(), and warn if an overflow is ever triggered. In gss_encode_v0_msg, replace the runtime BUG_ON() with an appropriate compile-time BUILD_BUG_ON.
