cdcontrol relative address track off-by-one fix

[Ben Woolley]

Before the patch, I would do:
cdcontrol 1 0:15
and it would play from track 2, 0:15, not track 1.
That seemed to be caused by tr1-- being after toc_buffer[tr1], and
toc_buffer[1] is track 2.
I looked for similar problems, but did not find any.

Cheers,

Ben Woolley
