What it means
To lark about is to play and mess around in a carefree, high-spirited way, full of jokes and silly antics with no real purpose but fun. The lark here is the playful sense of a bit of mischief and adventure, not the bird. Kids lark about in the playground, mates lark about on a night out, and someone larking about is enjoying themselves and not taking anything too seriously.

Where it comes from
It comes from the older English noun lark meaning a frolic or a bit of carefree fun. That sense is well established in British English by the 19th century, and lark about grew naturally from it as the verb phrase for messing around, clowning about, and having a laugh instead of doing anything useful.
