Pass envp, not environ, to real execve() from exec_wrapper() if possible.

Browse Source 
The replacement execve() function was passing the global environ
to exec_wrapper() instead of the envp parameter.  This caused the
command to be run with the wrong environment on AIX systems, and
possibly others, when intercept or log_subcmds was enabled.
Bug #1030.
