Bugfix: load_images cleanup, shellcheck fixes

We should have run shellcheck on this.

This is why we don't use the shell, too many
obscure gotchas.

shellcheck: load_images.sh:25:75: warning: sudo doesn't affect redirects. Use .. | sudo tee -a file [SC2024]

  sudo echo foo >> /etc/foo won't work,

the >> will be run in the current shell,
replace with:

  echo foo | sudo tee -a /etc/foo

shellcheck: load_images.sh:47:15: warning: Declare and assign separately to avoid masking return values. [SC2155]

replace local cmd='a' with two line version

shellcheck: load_images.sh:141:32: error: [ .. ] can't match globs. Use [[ .. ]] or grep. [SC2081]

use [[ ]]
