image_types.bbclass: fixed 'init' creation for cpio images

When /init is a dangling symlink or a symlink to a file which can not be
stated on the build system (e.g. due to SELinux restrictions), the '[ !
-e .../init ]' test will succeed which causes the manual creation of
/init.

E.g. here:

| $ ls -la cpio_append/init
| lrwxrwxrwx. 1 ensc ensc 10 22. Jan 16:26 cpio_append/init -> /sbin/init
|
| $ strace /bin/test -e  cpio_append/init
| stat("cpio_append/init", 0x7fff374a9db0) = -1 EACCES (Permission denied)
| exit_group(1)                           = ?

To test for the existence of a file, both '-L' and '-e' checks must be
executed and to prevent SELinux noise, the '-L' should happen before
'-e'.
