musl-legacy-compat: add fflush call to error().

Browse source 
The testsuite for elfutils expects things printed to stdout before
calling error() to appear before the error message; glibc implements
this by calling fflush(stdout) after checking the stream is still valid.
Here, we will simply flush all output streams.
