Fix typos in __sk_buff.md documentation

Noticed some typos while reading through the docs.
PACKET_HOST -- "Packet is addresses" should be "Packet is addressed"
PACKET_OTHERHOST -- "packet to addressed" should be "packet is addressed", replacing "that it has been caught by" with "but has been caught by" reads better and makes the message clearer.
PACKET_OUTGOING -- "Indicates that the packet originates from the local host and is looped back to a packet socket." is a bit more grammatically correct and easier to read than "indicates the packet originating from the local host that is looped back to a packet socket"
