remove the explicitly added "broken packages"

Hiding problems barely solves them.

 - drivers/camera_ids is automatically excluded by autoproj
 - the imar and stim300 packages should be present. Got migrated
   to github and if they don't build it should be FIXED not HIDDEN
 - if slam/ceres_solver does not build on some OSes, make sure that
   it is properly done by marking the relevant osdeps as 'nonexistent'
 - some "broken" packages should not be "broken" so wtf
 - and then 'others' ... really helpful
