image.bbclass: Use 'populate_sdk_base' for non-linux targets
When 'populate_sdk_ext' was first introduced in commit
bf81d6bb7f6 it
replaced the inheriting of 'populate_sdk_base'. For non-linux targets
building the extensible SDK caused build errors, and the image class was
changed to inherit 'populate_sdk' when targeting a non-linux SDK_OS (in
commmit
e471ce3464d). However inheriting 'populate_sdk' instead of
'populate_sdk_base' causes the SDK to always be built, this is not
expected for the image class.
This change makes the image class inherit 'populate_sdk_base' in the
non-linux SDK_OS case so that it behaves the same as it is expected to
behave where 'bitbake <image> -c populate_sdk' must be executed to
generate the SDK deployables.
