meta/lib/oe/package_manager.py: warn about failing scriptlets for all package types

Previously this was done only for rpm packages; now also ipk/deb scriptlet
failures are reported.

In the future this will become a hard error, but it can't yet happen
due to the legacy 'exit 1' way of deferring scriptlet execution to first boot which
needs a deprecation period.
