Subject: [PATCH] bitbake: toasterui: fix layer identification for managed
 builds

If we have a managed build, we match the layers used for build
with the layers configured for project, as we know where the layers
are coming from

[YOCTO #6962]

(Bitbake rev: e02ec052a62cbc476bdac65cb7cea1167ce04781)
