build: Bail on error

If one is missing one of the deps (e.g. yq for android devices) we should abort early instead of continuing and producing potentially confusing errors down the road.

This would need a bit more changes:

• there are a few occurences of [ -f <file> ] && ... which will error out if the file doesn't exist
• it would be a good opportunity to drop all || exit 1 as they wouldn't be needed anymore
