[PATCH] meta: image: detect broken symlinks

[Henning Schild <henning.schild@siemens.com>]

Switch get_image_name from os.path.lexists to os.path.exists because the
latter detects broken symlinks correctly.

Issue:
If you build a kernel without CONFIG_BLK_DEV_INITRD the postinst hook will
still call "linux-update-symlinks" and create a broken symlink. After
that os.path.lexists will return True and "sudo cp" in do_copy_boot_files
will fail.
