An even easier solution might be to *not* set up the signed tags in the
'setup' part, but only in the respective test case, and delete them right
away after said test case?

Something like this (I even tested this with and without the GPG prereq):

Subject: [PATCH] Do not make t6302 depend on gpg wholesale

There is but a single test case, in fact, that depends on gpg. Let's just
make the other test cases independent of gpg and add the GPG prereq to
said single test case.

Noticed by Eric Sunshine.
