[PATCH] maint.mk: fix typo in code to derive GPG key at release time

[Jim Meyering]

FYI, since I let the default GPG-key-deriving code get my key from
the just-created tag (the default), I noticed that it was broken.
This fix matters only at release time, and if you don't set
gpg_key_ID in cfg.mk:
