[OE-core] [PATCH 2/2] nativesdk-buildtools-perl-dummy.bb: Fix variable expansion in python code

[Aníbal Limón]

Since python expansion of bb data variables is disable in order to
provide a standard interface usage for expand variables this variables
aren't expanded now so change to call d.expand('${VAR}').

This API expansion change was causing to install perl in nativesdk.
