Wait for update.sh|cmd to finish instead of waiting 5 seconds - before restarting a runner (#2044)

* update.sh new logic with creating a file and waiting for it for 30 sec

* pr refactor

* removing file when it's detected bu run-helper

* Update src/Misc/layoutroot/run-helper.sh.template

Co-authored-by: Ferenc Hammerl <[email protected]>

* clean up update.finished in Runner.Listener right before it starts a process _update.sh

* pr fix IOUtil.DeleteFile

* self update widnows version - cmd

* same logic for returnCode 4 - ephemeral

* Init var so cmd doesn't run into syntax errors

* Use constants, setting a var messed up ERRORLEVEL

* Use var for updatefile
