[PATCH] iotests/testrunner.py: refactor test_field_width

[Vladimir Sementsov-Ogievskiy]

A lot of Optional[] types doesn't make code beautiful.
test_field_width defaults to 8, but that is never used in the code.

More over, if we want some default behavior for single call of
test_run(), it should just print the whole test name, not limiting or
expanding its width, so 8 is bad default.

So, just drop the default as unused for now.
