[OE-core] [PATCH] image.bbclass: Fix 'vardepsexclude' mechanism for image_cmd_${FSTYPE}

[Igor Romanov]

Current mechanism doesn't allow to use any non-determenistic variable, except 'DATE' and 'DATETIME', inside IMAGE_CMD_${FSTYPE} prototype.

Passing 'vardepsexclude' values from IMAGE_CMD_${FSTYPE}, so users will be able to avoid taskhash mismatch problems.
