[PATCH weston] use _Exit instead of exit if client fails to exec

[U. Artie Eoff]

From: "U. Artie Eoff" <ullysses.a.eoff at intel.com>

exit() calls atexit() handlers and C++ destructors (e.g. a C++
weston module) which could destroy state that the main process
depends on (e.g. ioctl's, tmpfiles, sockets, etc...).  If an exec
fails, call _Exit() instead of exit().
