kmod-sched-cake: bump to 20180716

Bump to the latest cake recipe.

This backports tc class support to kernel 4.9 and other than conditional
kernel compilation pre-processor macros represents the cake that has
gone upstream into kernel 4.19.  Loud cheer!

Fun may be had by changing cake tin classification for packets on
ingress. e.g.

tc filter add dev ifb4eth0 parent 800b: protocol ip u32 match \
ip dport 6981 0xffff action skbedit priority 800b:1

Where 800b: represents the filter handle for the ifb obtained by 'tc
qdisc' and the 1 from 800b:1 represents the cake tin number.  So the
above example puts all incoming packets destined for port 6981 into the
BULK (lowest priority) tin.
