aacenc: Adjust the initial offset for PNS values
This commit adjusts the intial offset for PNS values, introduced
with commit f7f71b5795d708763eb0c55fe5e2cb051b2b69f4 earlier. This
commit shifts the value in such a way that no further offsets are
required in the aaccoder.c file. Earlier version of the PNS patch had 2 offsets in both the aaccoder and aacenc.
