Subject: `clog` is duplicating changelog lines


`clog` have to read the tag CHANGELOGTEXT (not macro) appropriately
as an array: --qf '[%{CHANGELOGTEXT}\n]'.
Whole array is read, so the <SEPARATOR> is used to extract the first
changelog.

Fixes: https://pagure.io/fedpkg/issue/581
Resolves: rhbz#2310713
JIRA: RHELCMP-14285
