Allow RPM to return total file sizes larger than 4GB

Allow RPM to return total file sizes larger than 4GB

When an RPM has a total content size over 4GB, the --qf parameter
needs to use LONGSIZE instead of SIZE to display the total package
content file size, likely to keep compatibility with code
expecting 32 bit friendly values.

Otherwise, if a package is larger than 4GB, RPM returns (none).
Since this is later given as input to Python's int(),
it will throw an exception due to (none) not being a number.
