Don't provide dib-run-parts

It was an oversight during v2 development for dib to start providing
dib-run-parts.  The intention was for dib to use a vendored
dib-run-parts directly from $_LIB and have no dependencies on
dib-utils at all.  By exporting dib-run-parts, we created an
unintentional conflict with the dib-utils package which provides the
same script.

Tools that depend on dib-utils are unaffected by this
(os-refresh-config).

The only tool that installs diskimage-builder and then assumes
dib-run-parts is available in the path is instack.  I have proposed
Ibfe972208df40fa092b11b5419043524c903f1b4 to modify that to use our
internal version.

Install ``dib-run-parts`` into the chroot environment
Currently this element copies the ``dib-run-parts`` used by
diskimage-builder outside the chroot to inside. However, note while
the interface remains the same this element may be provided in future
with a different interface.

dib no longer exports ``dib-run-parts``. Adding this was an
oversight made during v2 development, since ``dib-utils`` already
provides this. The ``dib-run-parts`` used internally
(``diskimage_builder/lib/dib-run-parts``) is not intended to be
used by external tools. If you require ``dib-run-parts``, you
should install the ``dib-utils`` package.
