[tools] winetest/dissect: Fix handling of skipped test unit.

[Francois Gouget]

close_test_unit() adds an entry in summary.txt for every test unit.
So the report parser must set $summary instead of manually adding a
redundant summary.txt entry.

This caused skipped tests to appear as '0 failures' in the index pages 
instead of 'skipped'. That's because close_test_unit() was adding an 
extra 'not-skipped' entry in summary.txt.
