[igt-dev] [PATCH i-g-t 2/8] lib/i915/perf: fixup converter script

[Lionel Landwerlin]

This script was previous run in python2, but because IGT is python3
only there are differences in what it generates. In particular the
attribute order differs in the tostring() of the ElementTree
function...

Reorder them alphabetically manually.
