bindings: Fix interface matching when searching
bindings: Fix interface matching when searching

Prior to this patch the default interface matching filter
specified the org.openbmc and xyz.openbmc_project interface
namespaces.  This results in missing attributes in other
namespaces.

Change the default match algorithm to filter out
org.freedesktop.DBus.ObjectManager interfaces only, so that
by default the complete set of interfaces are considered.

Resolves: openbmc/openbmc#2269
