Make os-refresh-config install.d hook run later

os-refresh-config relies on being able to run virtualenv, which is only
guaranteed to be possible after running 01-install-pip from the
pip-and-virtualenv element.

To guarantee this ordering, move
install.d/os-refresh-config-source-install/01-os-refresh-config to
install.d/os-refresh-config-source-install/10-os-refresh-config

And for consistency in script execution timing, move
install.d/os-refresh-config-package-install/01-os-refresh-config to
install.d/os-refresh-config-package-install/10-os-refresh-config
