util/lua-common: fix SCFileInfo bug & doc comment

The callback for FileInfo was returning the wrong value, resulting
in loss of some tuple values for one calling SCFileInfo in a script.

The documentation comment wasn't mentioning the sha items that are
pushed.

(cherry picked from commit 1315cb793b884140b51e9934ebbdc7493be22db5)
