snap: legacy needs to now it is legacy for re-exec
Metadata
Current evaluation
Merged #2311 fixed root re-exec invoking legacy Snapcraft with the correct interpreter, resolving LP #1795501.
Resolution: closed resolved
Reason: PR #2311 was merged; it explicitly prepends the interpreter when invoking the legacy Snapcraft script, preventing root re-exec from selecting the wrong interpreter.

Issue body
When running in in re-exec mode and re-exec'ing as root
the wrong interpreter is used. This is solved by calling
the snapcraft "script" by prepending the interpreter.
