Subject: [PATCH] darwin-rebuild: fix sudo invocation on High Sierra

The version of sudo on macOS 10.13 High Sierra does not support the
`--preserve-env=LIST` option syntax.

Override sudo with a shell function that checks for the availability of
this option syntax, and set PATH for the command being invoked with
`sh -c` otherwise.
