Do not enforce the source value for yum provider

W/o this issue, source for package is always being constructed
as an Internet link in case of RedHat/SUSE.

This is a problem as we may want to use no source in case of
yum provider.

The solution is to not construct the real_package_source for yum
provider and use it as is.
