dkms.conf: Try harder when looking for ds.h

Some distros don't create /lib/modules/${kernelver}/source directory or
symlink, so the use of the
/lib/modules/${kernelver}/source/include/pcmcia/ds.h fails.  In this
case, use ${kernel_source_dir}/include/pcmcia/ds.h and hope for the
best.

This is useful for some versions of Ubuntu at least.
