When we add product name customization, we mistakenly defined the
parameter on each package build script.
Number of script is increasing since we recently added relocatable
python3 package, we should merge it in single place.
Also we should save the parameter on relocatable package, just like
version-release parameters.
So move the definition to SCYLLA-VERSION-GEN, save it to
build/SCYLLA-PRODUCT-FILE then archive it to relocatable package.

To align build system with scylla main repo, adding relocatable package
support.
On scylla-jmx, we don't provide libraries and linker since it's Java
program, just contains .jar file and dist/ directory.
