Fix printf format specifiers used for generating tarballs

When processing files > 4G, using "%o" truncates the result and the
tarball is not readable. This should have been discovered when
auto-patching the printf format specifiers, but a cast was added
instead and the issue was overlooked.

This commit replaces the down-cast and printf format specifiers.
