Binary provider:
It was not possible to remove the first glob in a local override,
because the mainPattern handling would re-add the first glob back.
XML provider:
It didn't support glob-deleteall.
Also, the order of the providers was wrong. We want to pick local
overrides first, the internal DB has to go last in the list.
Fixes: QTBUG-85436
