Add a helper for calling kernel-doc, with the -w parameter describing
the parameters to pass on to kernel-doc, in a special format.
[This is easier to explain and will make more sense in the context of
the following patches. The -w parameter is expected to be a filename
with the kernel-doc parameters encoded at the end of the filename. This
could be included in kernel-doc itself, but it feels like polluting the
tool. So here's a helper, at least for now.]
