[OE-core] [PATCH 2/9] classes/populate_sdk_ext: parse metadata on minimal SDK install

[Paul Eggleton]

Instead of skipping the build system preparation step within the
extensible SDK install process when SDK_EXT_TYPE is "minimal", run
bitbake -p so that the cache is populated ready for the first time
devtool is run.
