[OE-core] [PATCH] image.bbclass: fix a wrong position blank

[liu.ming50 at gmail.com]

From: Ming Liu <liu.ming50 at gmail.com>

A flaw was introduced by commit c5fa6034:
[ image.bbclass: use prependVarFlag for postfuncs ]

it changed to use prependVarFlag instead of appendVarFlag, then the
blank also needs change to adapt it.
