Subject: [PATCH] setup: only make one reference to env

If sys.executable happens to be '/usr/bin/env python' or something
similar, the setup script will result in 'ufw' getting /usr/bin/env
repeated on the top line.  This causes an error at runtime.  Perform a
quick sanity check on sys.executable before doing the substitution.

While we're at it, change the default value of 'exe' to the one we either
detected or specified on the build line.

Upstream-Status: Inappropriate [ embedded specific ]
