Honor make variable OUT_DIR in hyperkube Makefile
Needed to ensure the split of `make cross-in-a-container` and `make package-tarballs` honors the use of `OUT_DIR`.
In the new and upcoming containerized (GCB) release builds, multiple `cross-in-a-container` targets are run into their own `_output ($OUT_DIR)` directories and a second pass runs multiple `package-tarballs`.
This won't work unless we honor `$OUT_DIR` here.

Add 'exec' in all saltbase manifests using '/bin/sh -c'.
Right now, if docker sends SIGTERM, /bin/sh doesn't pass it to
underlying process, which breaks graceful process shutdown.
Changing '/bin/sh -c CMD > /var/log/FILE.log' pattern to '/bin/sh -c
exec CMD > /var/log/FILE.log' still allows to redirect output to log
file, but also passes all signals to CMD process.
