Programs cannot be launched in "plain" mode since the entrypoint conflicts with binaries

[Hugo Herter]

Uploading a program in "plain" mode requires an entrypoint that does not contain the name of the module ("app" instead of "main:app"), however the presence of ":" in the entrypoint is used to differenciate between Python programs and executables to launch. When trying to use "app" as an entrypoint to a program in "plain" mode, the init attempts to launch an executable.
