src: add negation match on singleton bitmask value
This patch provides a shortcut for:
ct status and dnat == 0
which allows to check for the packet whose dnat bit is unset:
# nft add rule x y ct status ! dnat counter
This operation is only available for expression with a bitmask basetype, eg.
# nft describe ct status
ct expression, datatype ct_status (conntrack status) (basetype bitmask, integer), 32 bits
