[OE-core] [RFC v2][PATCH 3/3] buildhistory: remove duplicate entries from dot graph

[Koen Kooi]

There are various conditions that lead to duplicate entries in the dot graph which need to get fixed, but this patch is a catchall. A previous attempt to address this only works on rpm which gives a \n seperated output, opkg doesn't.

Another benefit is that the sort order is now know, leading to less spurious diffs in buildhistory commits.

Changes since v1: remove sort | uniq in the for loop, that only works with RPM
