Subject: [PATCH] Scripts: Handle "nothing installed" case gracefully for
 plugin builds

When (temporarily) turning off the QmlDesigner build, the separate
QmlDesigner plugin repository build results in nothing being installed.
The 7zip call and signing code then fails if the installation directory
isn't even created as a consequence.
