ar71xx: unbreak building images for OpenMesh OM2P/OM2P-LC

Commit r33248 introduced a regression by passing the board name plus
'board=' in the third argument. The board name string has to be put
into the image as identifier of the image type.

[juhosg: fix OpenMesh template instead of use of string substitution]
