Expand trap cleanup function (#773)

Browse Source 
* build.sh: Unmount intermediates on trap

Iterate through image files which might be in use and detach them

Avoid silent failures - let the user know whether the build failed

* common: update unmount_image

Use udevadm settle instead of sleep if possible

Use losetup's -j option to find the loop device associated with a give image file

* build.sh: update clean-up trap term
