[PATCH] t7004: check a missing key without deleting gpghome

["Harald Nordgren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Harald Nordgren <haraldnordgren@gmail.com>

The "verify signed tag fails when public key is not present" test
deletes gpghome to lose the key, and this sometimes fails on Alpine
with

    rm: can't remove 'gpghome/S.gpg-agent.extra': No such file or directory

Point GNUPGHOME at an unused directory for the verification, which is
how t7510 checks a signature whose key is unknown.
