[oe] [PATCH] kernel.bbclass: fixed dependency calculation with recent modutils

[Enrico Scholz]

'depmod' from  recent module-init-tools (version 3.9 or later) returns
paths relative to /lib/modules/`uname -r`.  E.g. 'modules.dep' contain

| kernel/fs/nfs_common/nfs_acl.ko: kernel/net/sunrpc/sunrpc.ko

instead of absolute pathnames.

The dependency calculation of kernel modules depends on absolutes paths
which are readded by this patch.
