Remove Translate preferences from incognito whitelist.

Preferences defined in
  'components/translate/core/browser/translate_pref_names.h'
  'components/translate/core/browser/translate_prefs.h'
are removed from the persistent storage list for incognito mode.
This means that after this CL, these preferences are only stored in
memory in incognito mode.
