hyperstart: remove recipe

Browse Source 
hyperstart is in read-only mode, so we drop it from the layer.

A replacement will be provided in the future.

Subject: [PATCH] container.c: Fix compiler errors that gcc 8.1.0 reports
gcc 8.1.0 reports the following compiler errors/warnings. They can be
fixed by using snprintf and checking the result for truncation. This
patch also uses a named constant instead of inserting the value 512 in
many locations.
container.c: In function 'hyper_setup_container_rootfs':
container.c:630:24: error: '/' directive writing 1 byte into a region of size between 0 and 511 [-Werror=format-overflow=]
sprintf(rootfs, "%s/%s/", root, container->rootfs);
^

^~ ~~~
container.c:262:2: note: 'sprintf' output between 3 and 514 bytes into a destination of size 512

^~~~~~
