Add semicolon to "Maybe a missing `extern crate foo`" message

I had it a couple of times that I was missing the "extern crate" line
after I introduced a new dependency. So I copied the text from the
message and inserted it into the beginning of my code, only to find the
compiler complaining that I was missing the semicolon. (I forgot to add
it after the text that I had pasted.)

There's a similar message which does include the semicolon, namely
"help: you can import it into scope: `use foo::Bar;`". I think the two
messages should be consistent, so this change adds it for "extern
crate".
