[PATCH] tests: gpt: do not munge GPT data manually

[Jim Meyering]

Otherwise, an upcoming change would cause this test to fail.
* tests/t5000-tags.sh: Do not munge GPT data manually, since that
does not update embedded CRCs, and thus renders it invalid.
Set the attribute via "set 1 bios_grub on" instead.
Also, use "name1" as the partition name, rather than the
misleading "primary".
Adjust diagnostics: the changes we make are no longer "manual."
