[v3 PATCH 2/17] main: Only set savestatus in exitcmd

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

Currently exitcmd sets exitstatus and then savestatus if the latter
was previously set.  In fact, as exitcmd always raises an exception
and will either end up in the setjmp call in main() or exitshell(),
where exitstatus is always replaced by savestatus if set, we only
need to set savestatus.
