[11u] RFR: 8232834: RunTest sometimes fails to produce valid exitcode.txt

[Lindenmaier, Goetz]

Hi,

I had to resolve this manually.
The original change introduces brackets after each
ExecuteWithLog statement.
In 11, these statements look different so that the patch
does not apply.

I checked all occurances of this statement and added
the brackets accordingly.
