[OE-core] [PATCH] wic: Prevent duplicate entries on fstab

[Fabio Berton]

Hi Ross,

Sorry for delay. This error for qemux86 is because common.wks.inc and 
directdisk-gpt.wks files in scripts/lib/wic/canned-wks directory doesn't 
have option --fstype= for part /boot.

For qemuarm machines I get the error:

| DEBUG: Executing python function set_image_size
| DEBUG: Python function set_image_size finished
| DEBUG: Executing shell function do_image_wic
| Error: Please build syslinux first
