tools/flask/utils: remove unused variables/targets from Makefile

They are no *.opic or *.so in this subdir, so no need to clean them.

The TEST* variables doesn't seems to be used anywhere, and they weren't
used by xen.git when introduced.
Both CLIENTS_* variables aren't used.
Both target "print-dir" and "print-end" only exist in this directory
and are probably not used anywhere.
