[OE-core] [PATCH] lib/oe/rootfs: prelink only when image-prelink is inherited

[Andrej Valek]

Use prelink only when image-prelink class is inherited. Inheriting this
class adds prelink-native as dependency to do_rootfs, which makes prelink
binary and configuration available.

|Exception: FileNotFoundError: [Errno 2] No such file or directory:
|'/home/.../1.0-r0/recipe-sysroot-native/etc/prelink.conf'
|
| if not os.path.exists(prelink_cfg):
|     shutil.copy(self.d.expand('${STAGING_DIR_NATIVE}${sysconfdir_native}/prelink.conf'),prelink_cfg)
