[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
 127
