tools/pyboard.py: Move --no-exclusive/--soft-reset out of mutex group.

The --no-exclusive flag was accidentally added to the mutex group in
178198a01d.

The --soft-reset flag was accidentally added to the mutex group in
41adf17830.

These flags can be specified independently to --[no-]follow so should not
be in that mutex group.
