patch

As reported here: https://bugs.launchpad.net/soundconverter/+bug/1075497
The xing header frames count in mp3 generated with gstreamer's xingmux always
have two frames missing.

After a verification of the xingmux code, I propose a small fix:

First, the xing header frame is never added to the count, we have to increment
the count.
Secondly, there is a rounding error when calculating the frame duration, as
spf*GST_SECOND/rate is not an integer (26122448.9) an it must be 26122449.
