CPackRPM: %pretrans scriptlet violates guidelines

according to, say, Fedora guidelines (https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/)

Note that the %pretrans scriptlet will, in the particular case of system installation, run before anything at all has been installed. This implies that it cannot have any dependencies at all. For this reason, %pretrans is best avoided, but if used it MUST (by necessity) be written in Lua

The syntax for that is %pretrans -p <lua>
