acmd.py loads all available plugins (modules in its script directory)
each time it is executed. Removing unnecessary imports at the module
level speeds up this process significantly. For example, removing the
unnecessary ROOT import in diff_root_files.py saves 2 out of the 3
seconds when running `acmd.py -h`.

Removing references to PyCintex, Reflex and ROOT6Setup from PyUtils
as final cleanup after the ROOT6 transition
ROOT6Setup remains in Helpers as it is still in use by other packages
Note: Dso.py was earlier disabled and this commit does not fix it
