Fixes [Yocto #2036]
The source and build directories are unused, remove them.
The modutils and modprobe.d directories may be used if modules are built that
are either autoloaded or have modprobe.d entries. This isn't known at install
time, so check after the package split if these directories are empty and
remove them if they are.

How do you want to support on-target building of exernal modules?
That is an open issue that needs to be addressed, but we don't install
the build or source directories now (unless I'm missing something), so
these are links to nowhere at the moment.
We do have a bug open to support on-target module building. I supect
we'll need to add these as part of a headers package or similar. So
these may come back.
Just as a note.. headers package(s) are the wrong way to support kernel modules
compilation on the target. You really need to supply a configured kernel source
tree --- often you can dump the .c files though. Kernel headers (for module
compilation) and userspace are often intentionally different.. and people get
this confused often. (I can't express how often I've had to convince someone
that, no you can't guaranty a working kernel module from the stuff in /usr/include!)
The right approach is to provide, as part of the kernel itself, a source
tree/headers package tha installes into the
"{D}/lib/modules/${KERNEL_VERSION}/source" (or similar) directory, and instruct
people to use that location when building kernel modules on the target.
