build_image: Fix shellcheck warnings
In preparation for turning on shellcheck more widely, clean up the
existing lint warnings. This isn't completely clean with the shellcheck
currently in the chroot, but the remaining warnings will be gone once we
have shflags support in shellcheck (tested with a local patch).
