[ibex] Pass mvendorid and mimpid also to lockstep core

Browse source 
Otherwise an alert is raised if a core has a different
configuration than zero. There, the primary core would
return the non-zero value but the lockstep core zero.
This difference causes an alert.

This PR fixes this bug and passes the mvendirid and mimpid
parameters also to the lockstep core so that they are in sync
