Adjust tags for test filename-length-really-really-really-really-long-package-name.

Using source format "3.0 (non-native)", the longest name of any member
is, at 111 characters:

    filename-length-really-really-really-really-long-package-name_1.0.and.a.really.long.version.too-1.debian.tar.xz

While with source format "1.0", the longest name is, at 107
characters:

    filename-length-really-really-really-really-long-package-name_1.0.and.a.really.long.version.too.orig.tar.gz

The difference in the lengths of these two filenames is the reason for
the tag change herein.
