sculpt: inform user about incomplete pkg install

This commit handles the corner case where a package could be installed
successfully but the package's runtime definition is inconsistent with
the content delivered by the package's dependencies, i.e., the <content>
of the runtime file lists ROM modules that do not exist.

With this patch, the '+' menu shows the message "installed but
incomplete" whenever a package is in such a state.

Issue #3241
