Avoid backtraces on expected failures when built with ghc 8; only use backtraces for unexpected errors.
ghc 8 added backtraces on uncaught errors. This is great, but git-annex was using error in many places for a error message targeted at the user, in some known problem case. A backtrace only confuses such a message, so omit it. Notably, commands like git annex drop that failed due to eg, numcopies, used to use error, so had a backtrace. This commit was sponsored by Ethan Aubin.
