Change strlcat function name from redis to valkey (#440)

Browse Source 
Updated strlcat function and macros name (redis_strlcat ->
valkey_strlcat).

I think the standard strcat function is not safe.
(https://codeql.github.com/codeql-query-help/cpp/cpp-unsafe-strcat/)
So, it would be better to keep it as a safe function.
