nativesdk.bbclass: Correct ordering of manipulations
OVERDIDES is the key variable that needs to be set prior to data finalisation.
The other variables should be manipulated after finalisation so any
DEPENDS_prepend and _append are accounted for. This patch ensures this is
the case.
The PACKAGES maniupulations are not enabled at this time as they
don't function 100% correctly yet.
