monitor: Fix file_completion() to check for stat() failure 

stat() can fail for a file name just read with readdir().  Easiest way
to trigger is a dangling symbolic link --- look ma, no race!  When it
fails, file_completion() uses sb.st_mode uninitialized.  If the
directory bit happens to be set, it appends a "/" to the completed
name.
