[tools] winetest/dissect: Improve the pid detection on garbled lines.

[Francois Gouget]

The pid is always printed with a fixed width so this should be taken
into account to avoid matching too much. For instance in
'garbage1234:unit.c:...' one should match '1234', not 'e1234' which
would lead to a mismatch with the pids on other lines.
This is particularly important for the exception, summary and done
lines.
This also means the matching can be simplified a bit since we know
where the relevant part of the line starts.
