Add Never/Always translate buttons to the translate infobar on Linux.

BUG=None
TEST=Visit a page in a language different than the browser language. On the translate infobar, select 'Nope' (don't translate). Repeat 4 times, the 4th time a button 'Never translate' should be available. Test that pressing this button works as expected (further navigations to page in that specific language should not bring a translate infobar).
     Follow the same steps but now click on Translate. You should get an "Always translate" button on the 4th time.
