ipq40xx: Change name for openmesh.sh to vendor-free name

Other vendors are using functionality similar to the ones OpenMesh used to
implement two areas on the flash to store the default image and a fallback
image. So just change the name to dualboot_datachk.sh to avoid duplicated
code just to have the same script for different vendors.
