  [llvm-objdump] Simplify reportError() and prepend outs().flush()

As noticed by dblaikie.

I don't know what code paths using reportError can cause stdout output
to be interleaved with stderr, so no test is added now.

Also drop an unneeded use of errs().fflush() in reportWarning().
I requested this in D64165.
