[PATCH] linux-user: Flush errors by using exit() instead of _exit() in error path

[Helge Deller <deller@kernel.org>]

From: Helge Deller <deller@gmx.de>

Qemu user mode does not properly flushes error messages related to bad
arguments when exiting (at least when the output is piped to a file
instead of running on a terminal).
Ensure that we always flush by using exit() instead of _exit().
