audio/internal/readerdriver: Bug fix: createBuffer failed when the buffer size is 0

Browse Source 
When the decoded audio size is exactly multiples of an internal
buffer size, the buffer's size becomes exactly zero when being
appended. In this case, createBuffer fails and the application
crashes.

This change fixes this issue by skipping to append a buffer in such
cases.

Closes #1635
