arc: Indentation fixes

I'm testing my new app called 'inspekt', and found out
that arc has quite a few trailing whitespaces in lines.
This patch fixes them.

arc: Add missing 'modify' methods

Pylint caught the absence of 'modify' methods for ACLs,
Atomic Groups and Labels. Nevertheless, they were all
being exported in the variable __all__. From my very
poor understanding of the code base, the methods that
modify said objects are implemented by this patch.

The correct class name available on that namespace

They were only a few, so I thought, 'why not?'
