The etcd 3.6.1 image build fails to build the 3.6.1 binary

[Timothy-Dougherty]

recent changes to the etcd repo have moved the location of the build script

from

./build.sh

to

./scripts/build.sh

recent build logs show the issue as:

HEAD is now at a4708beb0 version: bump up to 3.6.1
/bin/bash: line 1: ./build.sh: No such file or directory
done
