make_file: always return a fresh file handle that can be closed
Currently, cmdutil.make_file() will return a freshly made file handle,
except when given a pattern of '-'. If callers would want to close the
handle, they would have to make sure that it's neither sys.stdin or
sys.stdout. Instead, returning a duplicate of either of the two
ensures that make_file() lives up to its name and creates a new
file handle regardless of the input.
