[Submodule update] sonic-py-swssdk

78f167e4728f939712b3f3ea550949e2ea675fec With the changes in PR:sonic-net#5289 access to redis unix socket is given to the redis group members. Many of sonic-util commands (especially in multi-asic) case use redis unix socket to connect to DB and thus those comamnd fails without providing sudo. This PR is continuation  of PR: sonic-net#7002 where we default to use TCP for Redis if user is not root
