Fix initializer syntax for old Xcode compiler (#6662)

Summary:
Example compiler output, from OSX TEST_GROUP=3:

db/flush_job_test.cc:185:7: error: suggest braces around initialization
of subobject [-Werror,-Wmissing-braces]
      kInvalidBlobFileNumber, 5, 103, 17, 102, 101};

Apparently permitted in newer version, but worth working around.
