binop: take care of operator precedence when printing binop arguments
When the argument of a binop is a binop itself, we may need to add parens
if the precedence of the argument is lower then the binop.
Before:
tcp flags & syn | ack == syn | ack
tcp flags & syn | ack != syn | ack
After:
tcp flags & (syn | ack) == syn | ack
tcp flags & (syn | ack) != syn | ack
