tests: Extend tests with an ultimately trusted key
* tests/gpg/Makefile.am (gpg-sample.stamp, pubring-stamp): Unify usage
of tabs.
(pubring-stamp): Import owner trust values.
* tests/gpg/ownertrust.txt: New.
* tests/gpg/t-decrypt-verify.c, tests/gpg/t-verify.c: Update expected
values for signature summary and validity.
* tests/gpg/t-keylist-secret-sig.c, tests/gpg/t-keylist-sig.c,
tests/gpg/t-keylist.c: Update expected values of owner trust and uid
validity.
--

This change marks the "Alpha Test" test key as ultimately trusted which
makes it possible to check for correct values derived from this, i.e.
key owner trust, user id validity, signature summary and signature
validity.
