linux-user: implement reboot syscall
For OBS, we're running a full cross-guest inside of a VM. When a build
is done there, we reboot the guest as shutdown mechanism.
Unfortunately, reboot is not implemented in linux-user. So this mechanism
fails, spilling unpretty warnings. This patch implements sys_reboot()
emulation.
