Ian Rogers 1059fb5291 perf dsos: When adding a dso into sorted dsos maintain the sort order 
dsos__add would add at the end of the dso array possibly requiring a
later find to re-sort the array. Patterns of find then add were
becoming O(n*log n) due to the sorts. Change the add routine to be
O(n) rather than O(1) but to maintain the sorted-ness of the dsos
array so that later finds don't need the O(n*log n) sort.

Fixes: 3f4ac23a99 ("perf dsos: Switch backing storage to array from rbtree/list")
