git and the patch command expect file to end with a new line.

Set -o pipefail new scripts

A few scripts were added without set -o pipefail since the original
change to add that everywhere.  This will get the dib-lint check
passing again.

Check for set -o pipefail

Like the other set lint checks, this will hopefully catch errors
in element scripts sooner.
