stubgen: increase get_package_properties timeout (#13109)

mwoehlke-kitware · web-flow · commit 7c6faf4c7a7b · 2022-07-13T13:30:23.000-07:00
Some packages may take a very long time to import, which can spuriously
trip the timeout in ModuleInspect. To make this less likely, increase
the timeout from 5s to 30s.
