Title: Fix for issue #604

This is a fix for issue #604 which caused stylus to crash when using
--line-numbers or firebug and stein at the same time. This was caused
by trying to call fs.realpathSync with a bogus file named stdin.

Obviously there is no path to include in the line numbers when using stdin, so I just used 'stdin' as the path name and prevented the call to fs.realpathSync which was causing the crash.
