[tools]winetest: fix child-result coloring and counting

[André Hentschel]

You can see wrong coloring e.g. here http://test.winehq.org/data/f74e312bf81032c46bd2ce080a5f6a33c7ac3ee3/wine_ah-910-64-nv/rpcrt4:server.html
Also the counting is wrong, that unit test is shown in the summary with 2 errors, but only has 1
This patch fixes the issue. The totalize of those variables is already made in the "offline" software
