Code Issues Proposed changes

Fix incorrect entrypoint for updated image

Browse Source 
Modify update-stx-image.sh to format the original CMD and ENTRYPOINT as
an array of tokens. For example ["token1", "token2"] or [""].
This way `docker commit --change` behaves as expected.

Tested on:
ORIG_CMD=/bin/bash
ORIG_ENTRYPOINT=

ORIG_CMD='/bin/bash -c'
ORIG_ENTRYPOINT=/bin/bash
