insane.bbclass: fix override handling in RDEPENDS QA
The package_qa_check_rdepends() in insane.bbclass has
incorrectly replace its localdata OVERRIDES value with
the package name. Fixing it by appending the package name
to the existing OVERRIDES value. This resolves RDEPENDS QA
error when setting PACKAGECONFIG using a pn- override at
local.conf.
