image/populate_sdk: Support usrmerge in toolchain SDK builds

SDKs which aren't built from an image recipe should also come with
drop-in symlinks for `/bin`, `/lib` and `/sbin`. Support this by moving
the common functionality into `populate_sdk_base` and enabling the
symlink creation when the `usrmerge` DISTRO_FEATURE is on.
