module.bbclass: Create a new depmodwrapper to assist cross-installs

Previously the build path to STAGING_KERNEL_DIR was being embedded into the
package post install scripts.  We avoid this behavior by generating a special
depmodwrapper script.  This script contains that hard-coded path, ensuring
that re-use of the sstate-cache (and/or packages) will always run through the
wrapper generated by the current build with a checksum that includes
STAGING_KERNEL_DIR.
