Remove duplicate script entry leading to broken wheel build

The entry_point option already defines the /bin/swift script implicitly.
The definition of `scripts=bin/swift` ontop of that leads to a corrupt wheel build and can lead to a collision error during installation:
FileExistsError: File already exists: [...]/bin/swift
