Remove unnecessary rules from .gitignore

[fotonmoton]

Remove run*, test* and example-deconstructor* example-reformatter* rules from .gitignore.

Case:

1. Download lib from Github.
2. Add lib to your project
3. Push your project to Github.
4. Pull your project from Github.
5. Try to compile your project with libyaml.

Expected result:

• All comiles and work

Actual result:

• Libyaml doesn't compiles because of missing files (test files)

Error that I get:
make[2]: Entering directory '/tmp/rt/lib/libyaml/tests' make[2]: *** No rule to make target 'run-scanner.c', needed by 'run-scanner.o'. Stop.

Note: I don't know why the run-* scripts were originally added to .gitignore.

A workaround: do git add -f libyaml, this will also add files that would be igored otherwise

I see this was changed in d050fe3
Seems this was an oversight.
