[BUGFIX] Update redefinition guard comments in SystemEnvironmentBuilder
These constant redefintion guards were forgotten to be updated when
Bootstrap::getInstance() and the call to SystemEnvironmentBuilder::run()
in Bootstrap::baseSetup() were removed.
These guards are no longer necessary for regular execution as baseSetup()
does no longer (conditionally) invoke SystemEnvironmentBuilder::run()
(which was provided for deprecated and now removed bootstrapping code).
We do still leave the guards in, as they are needed in unit tests,
but update the comments.
