Hidden dirs are not copied when creating the built product archive

Reviewed by Carlos Garcia Campos.

Hidden dirs are not copied inside the built product archive because
the recursive copy command was ignoring them. We need those hidden
directories for the GTK WebKit2 testing bot to work fine.

* BuildSlaveSupport/built-product-archive:
(archiveBuiltProduct): removed the trailing "*" from the copy
command.
