            Two small fixes for chain-build.sh (dedup + Pagure error check)

1. Dependent list isn't deduplicated. dnf repoquery --qf='%{source_name}\n'
prints one line per binary package, so a source package that ships several
binaries linking libtree-sitter shows up multiple times and gets
cloned/bumped/built repeatedly. Piping the grep through sort -u fixes it.

2. Pagure error-response check never fires. In if [[ $response == "{*" ]]
the whole pattern is quoted, so * is literal and it only matches the exact
string {*. A real error object like {"error":"..."} slips past and gets
treated as a PR URL. Quoting just the brace — "{"* — restores the intended
"starts with {" glob.
