Unnecessary timeout in diff tests

Reproduce the issue with ./test-run.py sql/gh-4111-format-in-sysview. -j1 from tarantool/test/, using the assertion shown in src/box/sql/parse.y. Start by tracing how test-run.py handles an aborted worker and result files; done means the diff is reported without waiting for the timeout while preserving the useful failure output.

If Tarantool is aborted, diff tests (at least from sql/) only produce diff after a timeout.

For example, let's say that we applied this diff:

diff --git a/src/box/sql/parse.y b/src/box/sql/parse.y
index fb9332c80..f65f91d57 100644
--- a/src/box/sql/parse.y
+++ b/src/box/sql/parse.y
@@ -399,6 +399,7 @@ ifexists(A) ::= .            {A = 0;}
 //
 cmd ::= createkw(X) VIEW ifnotexists(E) nm(Y) eidlist_opt(C)
           AS select(S). {

   if (!pParse->parse_only) {
     create_view_def_init(&pParse->create_view_def, &Y, &X, C, S, E);
     pParse->initiateTTrans = true;

And ran the following command in tarantool/test/:

./test-run.py sql/gh-4111-format-in-sysview. -j1

Result on the commit just before test: bump test-run to new version:

Note that the latter result is better because it shows the difference, but only after a timeout. It would be great if the timeout could be removed in such cases.
