exec: Don't format status returned directly from builtin function

Browse source 
The builtin function returns the raw status, which is not the same as
the integer return by waitpid. Therefore, the WIF macros shouldn't be
used for checking or obtaining the status.

This bug can be seen by executing (eval false). The builtin eval
function returns 1, but proc_format_status misinterprets it as a signal
by checking WIFSIGNALED, so adds 128 to the status to return 129.
