The steam and steamdeps included in the packages are specifically designed to be modified for other distributions. Go ahead and fold your changes into them for your packaging purposes, so people don't have to run separate scripts to run steam and install dependencies. This is covered in the license, under section 1.B.ii.
FYI, you may need to do additional work to comply with redistribution licenses for the libraries you include. I'm not a lawyer, so I don't know what that would be, but FYI.
