bsc_control.py: remove unused -i option

This option only served to demonstrate possibility of manually selecting
<id> field in CTRL protocol. Since the transition to generic ipa module
this is no longer exposed so the option became a no-op. Correspondingly
there's no need to explicitly initialize the RNG - the Ctrl class
handles random <id> generation internally.
