Hi,

This patch improves some coverage when listing all the origins (fixed outputs)
of some packages.  The procedure 'packages-direct-sources' already lists the
'origin' as inputs but is missing the 'origin' as 'patches'.  For an instance
of such, see the package 'ntp'.

Note that it is not recursive.  If an 'origin' is listed in 'patches' or
'inputs' and that origin also contains 'patches' which is another 'origin'
then it will be missed.  For now, it is not covered because it somehow adds
complexity without an instance (yet) of such case.

Cheers,
simon
