linux-user: add gcov support to preexit_cleanup
As we don't always take the normal exit path when running a guest we
can skip the normal exit destructors where gcov normally dumps it's
info. The GCC manual suggests long running programs use __gcov_dump()
to flush out the coverage state periodically so we use that here.
