git-check-attr: Fix command-line handling to match docs 

According to the git-check-attr synopsis, if the '--stdin' option is
used then no pathnames are expected on the command line.  Change the
behavior to match this description; namely, if '--stdin' is used but
not '--', then treat all command-line arguments as attribute names.
