Restore 4.13 behavior with single value tags in query format arrays

Rpm documentation actually states that you must use %{=TAG} for the case
commit 7f47cbbd7d1600ae280e48a655c9e870cf9361e0 was trying to fix, but
caused regressions in other situations. So the 4.12 behavior is little
more than accidental, rpm is actually supposed to error out here
(but doesn't, which is another bug).

This reverts commits 7f47cbbd7d1600ae280e48a655c9e870cf9361e0 and
ead9cdd587bbf052722f0f8598e0983e565e3415.
