Subject: [PATCH] test: remove util from common
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

util is loaded just for one use of util.format(). Replace it with a
string template. While we're at it, delete nearby lengthy comment
justifying use of fs.readFileSync().
