[PATCH v2 0/4] make t6302 usable even without GPG installed

This is a re-roll of [1] which aims to allow t6302 to be run even without GPG installed. Changes since v1:

* rather than converting existing signed tags to unsigned, make testing
  of unsigned tags a normal part of the script and just suppress testing
  of signed tags when GPG is missing (Junio)

* new patch: silence redundant warning about missing GPG

Eric Sunshine (4):
  lib-gpg: drop unnecessary "missing GPG" warning
  t6302: normalize names and descriptions of signed tags
  t6302: also test annotated in addition to signed tags
  t6302: skip only signed tags rather than all tests when GPG is missing
