ref-filter: fix %(symref) for pretty_print_ref()

Because pretty_print_ref() currently has no ref_item flag, but the implementation of %(symref) need this flag, so git tag --verify or git verify-tag cannot get the output of %(symref). Therefore, %(symref) will be fixed in this patch series.

This bug was discovered by Peff here:
https://lore.kernel.org/git/YUO63qy2%2F5wibY4%[email protected]/

on the other hand, git tag --verify --format="%(refname)" or git verify-tag --forrmat="%(refname)" does not show the fullref name, but seems to be similar to using %(refname:lstrip=2).

And git verify-tag --format="verify: %(refname)" c06b72d02` will output:
"verify: c06b72d02". They are wrong features, but because some scripts are using them, so our current approach is to keep them.

ZheNing Hu (4):
refs: let repo_dwim_ref() learn get symref itself and ref flags
ref-filter: provide ref_flags to pretty_print_ref()
verify_tag: use repo_dwim_ref() to get ref fullname and ref_flags
ref-filter: let tag verify use %(refname:lstrip=2) by default
