Add the new build-rocky.sh script.
Also fix pycrypto not being used on rocky by overriding the
pip packages being installed in the build-rocky.sh script
Added some checks for the case 'requirement' is not part of BUILD_PROJECTS
If requirements is not part of BUILD_PROJECTS, assume it was built already
before and set the REQUIREMENTS_TAGGED_PROJECT_REF according to current project.
Otherwise there'd be WHEELS set to something like "requirements:version--distro"
In local dev environment, there can be actions from previous build.
As we are appending actions for per-project build, clear the content
first from last image build execution.
