Add file search result for repoquery --whatprovides

File provides are not only present in file provides, but also in
normal provides. The code did not searched for file provides when
filter_provide() already gained a result. It means that for some
glob pattern, dnf5 provides incomplete results without the patch.

Closes: #1153
