Add keepalived

Add keepalived sysext
Currently there is no official container for keepalived, so this recipe builds it statically from a github tag.
It requires docker for the building process.

What we could do here is to put all the commands in a temporary "install" script (bash heredoc writing to ${SYSEXTNAME}/install), and then use docker run -v "${SYSEXTNAME}":/work /work/install to run it and prepare the binary in /work/usr/bin/.

I have updated the build process.

Thanks, works well now. I also wanted to test arm64 but am hitting the Docker hub API limit even though I just downloaded one image so far…

The updated version triggers
./create_keepalived_sysext.sh: line 25: ARCH: unbound variable

if  [ "${ARCH}" = "x86-64" ] || [ "${ARCH}" = "x86_64" ]; then

Does an unbound variable still fails inside a IF?

Tested the arm64 build and it worked, yet quite slow due to the qemu-user translation.
