osdict: Add set_install_script_preferred_injection_method()

Browse Source 
As not all unattended installations will be done by the same method,
let's have a wrapper around set_preferred_injection_method(), from
Libosinfo.InstallSript, in order to be able to properly set which is
going to be the preferred injection method for a script.
