dpkg/update-alternatives: Fix dpkg version of update-alternatives to be usable
The version of dpkg the updates-alternatives-dpkg recipe pointed
at no longer used a perl script but a compiled binary. This meant
the "all" architecture field was invalid, as as the sed operation
during do_patch. All things considered the separate recipe was
pretty pointless.
This patch moves update-alternatives back to being built as part
of the dpkg recipe. It also moves various functionalty to the .inc
file which it belongs and fixes building and packaging of the dpkg
perl modules.
