[OE-core] [PATCH v4 7/7] image.bbclass: create root symlinks in nativesdk target sysroot

[Amarnath Valluri]

To match with the target image, the generated nativesdk's target sysroot also
should have the root symlinks(/lib*, /bin/, /sbin). So, extended the
'create_merged_usr_symlinks' to reuse symlink creation part even for nativesdk
using POPULATE_SDK_PRE_TARGET_COMMAND.
