ecm.eclass: For kde.org projects, try to rename metainfo file real hard

- detect if we are inheriting kde.org.eclass
- detect if package name is not the same as upstream name (KDE_ORG_NAME)
- iterate through "${ED}"/usr/share/metainfo/
- if file contains KDE_ORG_NAME or similar, rename that to ${PN}${SLOT/0*/}
- otherwise, prepend "${PN}${SLOT/0*/}-" after ^org.kde.

Notably, this does not (yet?) trigger if a package ${PN} == ${KDE_ORG_NAME}
but different SLOTs. Should we just do that all the time?
