aplay: Fix invalid file size check for non-regular files

Browse source 
aplay tries to check the file size via fstat() at parsing the format
headers and avoids parsing when the size is shorter than the given
size.  This works fine for regular files, but when a special file like
pipe is passed, it fails, eventually leading to the fallback mode
wrongly.

A proper fix is to do this sanity check only for a regular file.
