ash: [BUILTIN] Use EXEXIT in place of EXEXEC
Upstream commit:

[BUILTIN] Use EXEXIT in place of EXEXEC
The intended semantics of EXEXEC are identical to EXEXIT, so
simplify by using EXEXIT directly.
Functional change: in edge cases (exec within a trap handler),
this causes the exit status from exec not to be clobbered.
For example, without this patch:
$ sh -c 'trap "exec nonexistent" EXIT'; echo $?
exec: 1: nonexistent: not found
0
And with it:
$ sh -c 'trap "exec nonexistent" EXIT'; echo $?
exec: 1: nonexistent: not found
