Add CLIENT_DEPRECATE_EOF to capabilities flag

Note that "\x8f\x80\x15" is in reverse byte order.
So the flag becomes 15808f.
15 - Authenticatin plugin length
80 - 10000000 (unused)
8f - 10001111 (the leftmost 1 is for CLIENT_SESSION_TRACK)

This is changed to 15818f.
15 - Remains the same
81 - 10000001 (the last byte says CLIENT_DEPRECATE_EOF enabled)
8f - 10001111 (remains the same)
