Update sccache to its master branch

[alexcrichton]

Ideally I'd like to soon enable sccache for rustbuild itself and some of the
stage0 tools, but for that to work we'll need some better Rust support than the
pretty old version we were previously using!

The new sccache prints out the stack trace in sccache.log. Could we disable it? Without symbols the stack trace is meaningless, and even with symbols the trace is so long and there are so many expected errors there it is just wasting the log space.

Sure yeah, I'll look into that.

We haven't had a failure in so long and I believe sccache's error reporting has improved so I've removed the log printing entirely
