Santiago Torres b42ca35e5c t7004, t7030: fix here-doc syntax errors
Jan Palus noticed that some here-doc are spelled incorrectly,
resulting the entire remainder of the test snippet being slurped
into the "expect" file as if it were data, e.g. in this sequence

	cat >expect <<EOF &&
	... expectation ...
	EOF
	git $cmd_being_tested >actual &&
	test_cmp expect actual

the last command of the test is "cat" that sends everything to
'expect' and succeeds.

Fixing these issues in t7004 and t7030 reveals that "git tag -v"
and "git verify-tag" with their --format option do not work as the
test was expecting originally.  Instead of showing both valid tags
and tags with incorrect signatures on their output, tags that do not
pass verification are omitted from the output.  Another breakage that
is uncovered is that these tests must be restricted to environment
where gpg is available.

Arguably, that is a safer behaviour, and because the format
specifiers like %(tag) do not have a way to show if the signature
verifies correctly, the command with the --format option cannot be
used to get a list of tags annotated with their signature validity
anyway.

For now, let's fix the here-doc syntax, update the expectation to
match the reality, and update the test prerequisite.

Maybe later when we extend the --format language available to "git
tag -v" and "git verify-tag" to include things like "%(gpg:status)",
we may want to change the behaviour so that piping a list of tag
names into

    xargs git verify-tag --format='%(gpg:status) %(tag)'

becomes a good way to produce such a list, but that is a separate
topic.
