Adds ghc-report-errors to turn off *GHC Error* buffer when nil

Browse Source 
ghc-mod now writes GHC errors to a new *GHC Error* buffer only if
report-ghc-errors has the value `t`. If a user wants to silence this
buffer, they should evaluate the following s-expression.

    (setq ghc-report-errors nil)

Fixes kazu-yamamoto/ghc-mod#618
