scripts: mkbootimg_rpi4.sh: Stop build on any kind of errors

Currently, even if an error occurs during image creation, the script
does not abort, which may result in incorrect image creation. In order
to avoid confusion due to this, if any kind of error occurs during the
build process, the build will be stopped.
