[oe] [meta-oe][PATCH] libdbi-perl: prevent native libdbi-perl depending on target perl

[Martin Jansa]

This is the only one with this behavior in the layers I have in LuneOS
builds, see:
http://jenkins.nas-admin.org/job/LuneOS/view/unstable/job/luneos-unstable_workspace-compare-signatures/56/console

I don't remember seeing it before perl-cross change, but there were quite a
few issues before so it's possible I've overlooked it before, it's not in
this jenkins job for warrior:
http://jenkins.nas-admin.org/job/LuneOS/view/testing/job/luneos-testing_workspace-compare-signatures/144/console
but that's because my fix was merged in warrior and your revert wasn't.
