Convert all exec calls to use mutt_envlist(), remove setenv function.

The documentation implies that all children processes will be affected
by the setenv command, so convert all the exec calls to use
mutt_envlist().

The setenv("GPG_TTY") call is no longer needed so remove it.

With that removed, there are no other setenv calls in mutt, so remove
the autoconf check and replacement function.
