[klibc] dash: [EVAL] Do not clobber exitstatus in evalcommand

[ dash commit 0d1fb088a4a16569260de4266d4bd359491c6bcd ]

All originators of EXERROR have been setting the exitstatus for
a while now.  So it is no longer appropriate to set it explicitly
in evalcommand.

In fact doing so may cause the original exitstatus to be lost.
